## Introduction

The Proven Re-offending Statistics Quarterly bulletin provides key statistics on proven re-offending in England and Wales. It gives proven re-offending figures for offenders, who were released from custody, received a noncustodial conviction at court, received a caution, reprimand, warning or tested positive for opiates or cocaine between April 2009 and March 2010. Proven re-offending is defined as any offence committed in a one year follow-up period and receiving a court conviction, caution, reprimand or warning in the one year follow-up or a further six months waiting period. This is referred to as a proven re-offence. This is the second quarterly bulletin in a new series. This series merges six previous measures of re-offending which were split across many publications into a single coherent overview of proven re-offending for the first time. It is a significant step forward for measuring re-offending as for the first time users can: 

 get figures for the total number of proven re-offenders in an area and 
the total number of offences they commit in a year; 
 see re-offending rates for adults, juveniles, drug misusing and prolific 
offenders measures on a consistent basis both nationally and locally; 
 measure individual prison and probation level re-offending on a 
consistent basis. 
 This quarterly bulletin presents the proportion of offenders who re-offend (proven re-offending rate) and the number of proven re-offences those offenders commit by age group, gender, ethnicity, criminal history, offence type, serious proven re-offending, prolific and priority offenders and drug misusing offenders. Also included are proven re-offending rates for different types of sentence and by individual prison, probation trust and youth offending team. Latest figures are provided with comparisons to the previous twelve months, April 2008 to March 2009 and the year 2000 in order to highlight long-term trends; 2000 is the earliest re-offending data that exists on a comparable basis. The accompanying 'Definitions and Measurement' document gives more information. www.justice.gov.uk/publications/statistics-and-data/reoffending/provenreoffending-quarterly.htm A full set of results is also provided at: www.justice.gov.uk/publications/statistics-and-data/reoffending/provenreoffending-quarterly.htm Measuring proven re-offending There is no agreed international standard for measuring and reporting reoffending. An offender's journey through the justice system can be a complex one; offenders can appear on numerous occasions. Measuring true re-offending is difficult. Official records are taken from either the police or courts, but they will underestimate the true level of re-offending because only a proportion of crime is detected and not all crimes are recorded on one central system. Other methods of measuring re-offending, such as self report studies, are likely to be unreliable. Therefore, this report aims to measure proven re-offending. Since re-offending is now measured on a consistent basis across all groups it is possible to tailor analysis of re-offending to meet specific requirements.  
This quarterly bulletin and the accompanying 'Early estimates of proven reoffending' www.justice.gov.uk/publications/statistics-anddata/reoffending/proven-reoffending-quarterly.htm present measures on four different levels to meet users' needs: 

 The headline measure - this is the main measure of re-offending and is 
presented for different demographic groups and by offence. To provide 
this **overview of proven re-offending**, offenders are tracked and their proven re-offending behaviour is recorded, taking the **first event**1 in 
the **relevant period** as the start point and subsequent events as 
proven re-offences.  
 
 A headline measure where the first event is related to criminal justice 
and offender management - this provides a realistic and relevant view 
of proven re-offending by disposal (sentence type), prison and probation trust. Offenders are tracked and their proven re-offending 
behaviour is recorded **within** each disposal (caution, court order, 
discharge from prison, etc) or operational unit (prison or probation 
trust) taking the first event **within** each as the start point and 
subsequent events as re-offences.  
 
 Early estimates of re-offending - these use shorter follow-up and 
waiting periods but otherwise measure re-offending in exactly the same way as the headline measure. This is intended to provide offender 
managers with an earlier indication of proven re-offending trends so they can adjust or build on offender management operational policy.  
 
 A re-conviction measure for use by payment by results - this is the 
measure used in the prison pilots since court convictions are more closely associated with costs to the Criminal Justice System. For more details please refer to Annex A. 
 For a more detailed explanation, please see the accompanying 'Definitions and Measurement' document at www.justice.gov.uk/publications/statisticsand-data/reoffending/proven-reoffending-quarterly.htm Consultation This quarterly bulletin has been developed in response to a consultation in late 2010 and early 2011 by the Ministry of Justice (MoJ) on "Improvements to Ministry of Justice Statistics". The main points from the consultation that affect this publication can be found in Annex B. Users The contents of the bulletin will be of interest to government policy makers, the agencies responsible for offender management at both national and local levels, providers, practitioners and others who want to understand more about proven re-offending. 

In particular there are two Ministry of Justice impact indicators2 which will be monitored using results from this bulletin; 

 adult and juvenile re-offending - the percentage of adult and juvenile 
offenders who re-offend, measured quarterly by local authority 
 the percentage of adults released from custody who re-offend measured 
annually, by prison Government policy makers also use these statistics to develop, monitor and 
evaluate key elements of its policies including those on payments by results, 
legal aid, sentencing guidelines and drug and alcohol policies. Offender management agencies use these statistics to gain a local understanding of the criminal justice system, understand performance and to highlight best practice. Key agencies include; the National Offender 
Management Service, Youth Justice Board, private and voluntary sector 
providers of prison and probation services and local authorities. 
 
As proven re-offending is related to the characteristics of offenders, the actual 
rate of proven re-offending will depend, in part, on the characteristics of offenders coming into the system. This actual rate provides users with 
sufficient information on what the level of re-offending is (eg in their local 
area) and how it is changing over time. This bulletin also presents an adjusted proven re-offending rate to control for differences in the composition of the offender group which can be used by those who want to understand how 
changes in types of offenders coming through the justice system drives reoffending. 
 This is the second bulletin in a new series of publications produced in response to a consultation. The Ministry of Justice has addressed the main issues from the consultation. We have separately announced plans for further analysis on proven re-offending rates using a two and five year follow up period and to develop a measure of re-offending while on license under probation supervision for publication in July 2012. 

If you have any feedback, questions or requests for further information about this statistical bulletin, please direct them to the appropriate contact given at the end of this report. 

Executive Summary This report provides key statistics on proven re-offending in England and Wales. It gives proven re-offending figures for offenders who were released from custody, received a non-custodial conviction at court, received a caution, reprimand, warning or tested positive for opiates or cocaine between April 2009 and March 2010.  Proven re-offending is defined as any offence committed in a one year follow-up period and receiving a court conviction, caution, reprimand or warning in the one year follow up. Following this one year period, a further six months is allowed for cases to progress through the courts. 

In the 12 months ending March 2010, there were around 680,0003 offenders who were cautioned4, convicted (excluding immediate custodial sentences) or released from custody5. Just under 180,000 of these offenders committed a proven re-offence within a year. This gives a one-year proven re-offending rate of 26.3 per cent. These re-offenders committed an average of 2.80 offences each - around 500,000 offences in total - 79 per cent were committed by adults and 21 per cent were committed by juveniles. 

- 
53.3 per cent of these offences were committed by offenders with 11 or 
more previous offences. - 
0.7 per cent (around 3,300) were serious violent/sexual proven reoffences. 
Recent Changes Compared to the previous twelve months' cohort, the proven re-offending rate was slightly lower at 26.3 per cent compared to 26.8 per cent. This trend held across most sub-groups. Over the same time-period, the average number of proven re-offences per reoffender decreased by 2.1 per cent from 2.86 to 2.80.  
(PNC) and are, therefore, not included. Therefore, this number does not represent ALL proven offenders. Please refer to the Definitions and Measurement document for more detail www.justice.gov.uk/publications/statistics-and-data/reoffending/proven-reoffendingquarterly.htm This means that numbers of offenders in this bulletin will be different from the numbers published in the Offender Management Caseload Statistics www.justice.gov.uk/publications/statistics-and-data/prisons-and-probation/oms-quarterly.htm.

## Longer Term Changes In The Longer Term For Offenders Included Between 2000 And April 2009 To March 2010, The Proven Re-Offending Rate Fell Overall From 27.9 Per Cent To 26.3 Per Cent. The Rate:

- 
fell over three times as much for adults than for juveniles 
- 
fell for offenders commencing court orders, for offenders discharged 
from prison, for offenders given a discharge, and for those given 
reprimands, warnings and first tier penalties6, but rose for offenders 
given cautions, fines and youth community penalties. 
- 
fell for offenders aged 15 to 29 and rose for all other age groups. 
- 
fell more for adult women (-2.6 percentage points) than adult men (-0.9 
percentage points). 

## Between 2000 And April 2009 To March 2010 The Average Number Of Proven Re-Offences Per Re-Offender Fell From 3.37 To 2.80, A Fall Of 17.1 Per Cent.

1 Quarterly data only available from April 2005 onwards

 Re-offending by age Between April 2009 to March 2010, as in previous years, 15 to 17 year old proven offenders had the highest proven re-offending rate at 34.7 per cent (Table 3). The proven re-offending rate falls with increasing age (after 15-17) as shown in Figure E2. Compared to 2000 the latest proven re-offending rate rose for 10-14 year olds and for those aged 30 or more, but fell for offenders aged 15 to 29. The largest decreases in the average number of re-offences per re-offender were among those aged in the 21-24 age group from 3.61 re-offences per reoffender to 2.70 (a fall of around 25 per cent).  
 

## Previous Offences Offenders With A Large Number Of Previous Offences Have A Higher Rate Of Proven Re-Offending And This Is True For Both Adults And Juveniles. Compared To 2000 The Largest Decrease In The Proven Re-Offending Rate Was Among Offenders Who Had 1 To 2 Previous Offences (-3.9 Percentage Points):

 Adult offenders with 11 or more previous offences represented 27.9 per 
cent of adult offenders in April 2009 to March 2010 but committed 62.6 
per cent of all adult proven re-offences.  
 For juveniles, there were 5,600 offenders with 11 or more previous 
offences and they had a proven re-offending rate of 77.5 per cent. This group make up only 5.0 per cent of juvenile offenders but committed almost a fifth (18.3 per cent) of all juvenile proven re-offences. 
 Re-offending by Index offence The offence that leads to an offender being included in the relevant year is called the index offence. In April 2009 to March 2010, as in most previous years, domestic burglary had the highest proven re-offending rate at 48.6 per cent (Table 5c) with sexual (child) offences the lowest at 9.8 per cent. The largest decrease between 2000 and April 2009 to March 2010 in the proven re-offending rate was for soliciting and prostitution, a decrease of 19.3 percentage points while motoring offences had the second largest decrease of 10.3 percentage points.  

 Adult proven re-offending In April 2009 to March 2010, there were around 570,000 adult offenders3. Just over 140,000 of these offenders were proven to have committed a re-offence within a year. This gives a one year proven re-offending rate of 24.9 per cent. The average number of proven re-offences committed by these re-offenders was 2.80. 

Compared to the previous twelve months, there has been a decrease in the proven re-offending rate of 0.5 percentage points from 25.4 per cent. Overall there has been a 1.3 percentage point decrease in the proven reoffending rate since 2000 (from 26.2 to 24.9 per cent). However, compared to 
2000 the offenders in April 2009 to March 2010 had characteristics which meant they were more likely to re-offend. This means that after controlling for offender characteristics the decrease was larger at 3.4 percentage points. 

1 Quarterly data only available from April 2005 onwards

## Proven Re-Offending Rates For Offenders Discharged From Prison Or Commencing A Court Order Between April 2009 And March 2010, There Were 197,000 Adult Offenders3

who were discharged from prison or commenced a court order. Just under 
71,000 of these offenders were proven to have committed a re-offence within a year. This gives a one year proven re-offending rate of 36.0 per cent. The average number of proven re-offences committed by these re-offenders was 3.27. 

Overall there was a 4.9 percentage point decrease (from 40.9 to 36.0) in the proven re-offending rate between 2000 and the twelve months ending March 2010 and a 20.9 per cent decrease (from 4.13 to 3.27) in the average number of proven re-offences per re-offender. 

Prisoner's proven re-offending Between April 2009 and March 2010, around 61,000 adult offenders3 were discharged from custody. Just under 29,000 of these (46.9 per cent) were proven to have committed a re-offence within a year. These offenders committed around 115,000 proven re-offences, an average of 4.03 each. 54.3 per cent of adult offenders discharged from custody were released from sentences of less than 12 months. These offenders had a one year proven reoffending rate of 56.6 per cent, an increase of 2.3 percentage points from 
2000 (54.3 per cent). 

1 Quarterly data only available from April 2005 onwards Adult proven re-offending rates by individual prison Among prisons which discharged thirty or more offenders between April 2009 and March 2010, re-offending rates varied considerably from 5.7 per cent to 87.5 per cent for offenders with a sentence of less than twelve months and from 5.8 per cent to 68.2 per cent for offenders with a sentence of twelve months or more. A large part of this variability reflects the mix of offenders who are held in different prisons and, therefore, comparisons between prisons should not be made using these raw re-offending rates. 

 
Among prisons discharging prisoners serving sentences of less than 12 
months only three had re-offending rates that were significantly different from the expected rate. Sudbury and Askham Grange had lower than expected reoffending rates while re-offending rates for Hindley were higher. Among prisons discharging offenders serving sentences of 12 months or more only, one prison had significantly lower re-offending rates (Usk/ Prescoed) than expected and one (Warren Hill) had higher. Proven re-offending of adults starting court orders  
 
Between April 2009 and March 2010, around 110,000 adult offenders3 started a community order. Around 38,000 of these (35.4 per cent) committed a proven re-offence within a year. These proven re-offenders committed just under 120,000 proven re-offences, an average of 3.16 proven re-offences each. Similarly, of the 38,000 adult offenders starting a suspended sentence order, 30.6 per cent committed a proven re-offence within a year, committing an average of 2.86 proven re-offences each. Proven re-offending rates by probation trust Offenders given a Court Order are managed by the probation service which comprises 35 Probation Trusts. Proven re-offending rates of these offenders are presented by Probation Trust in Table 24. This takes the first court order commencement from within each probation trust as the start point for measuring re-offending and subsequent events as proven re-offences. 

Re-offending rates varied considerably between probation trusts from 28.5 per cent to 43.5 per cent. A large part of this variability reflects the mix of offenders who are given a Court Order and therefore comparisons between probation trusts should not be made using these raw re-offending rates. For probation trusts an adjusted proven re-offending rate to control for differences in the composition of the offender group in each trust has been developed from the national model. Seven probation trusts showed significantly lower re-offending rates than expected. These were Cumbria, Gloucestershire, London, Staffordshire and West Midlands, Thames Valley, Warwickshire and West Yorkshire. None showed higher re-offending rates than expected. Re-offending rates by disposal (sentence type) should not be compared to assess the effectiveness of sentences, as there is no control for known differences in offender characteristics and the type of sentence given. The Compendium of Re-offending Statistics and Analysis 2011 compares like for like offenders which enables a more reliable comparison of proven reoffending rates between offenders receiving different sentences. 

The key results from the Compendium were:  

 those sentenced to 1 to 2 years in custody had lower re-offending rates 
than those given sentences of less than 12 months - the difference was 4.4 percentage points in 2008  
 custodial sentences of less than 12 months were less effective at 
reducing re-offending than both community orders and suspended sentence orders - between 5 and 9 percentage points in 2008.

Juvenile proven re-offending Between April 2009 and March 2010, there were around 110,000 juvenile offenders. Just under 38,000 of these offenders were proven to have committed a re-offence within a year. This gives a one year proven reoffending rate of 33.3 per cent. The average number of proven re-offences committed by these re-offenders was 2.79. Compared to the previous twelve months, there was an increase in the proven re-offending rate of 0.4 percentage points from 32.8 per cent. However, the number of juvenile proven offenders has decreased by 18.5 per cent since 2000. This is in line with the pattern of first time entrants to the criminal justice system where the number of young people receiving their first reprimand, warning or conviction has also decreased. More information on first time entrants for both adults and juveniles can be found in the Criminal Justice System Statistics Quarterly at: 
www.justice.gov.uk/publications/statistics-and-data/criminal-justice/index.htm 
 
Overall there was a 0.4 percentage point decrease in the proven re-offending rate of juveniles since 2000 (from 33.7 to 33.3 per cent). However, compared to 2000 the characteristics of juvenile offenders in the year ending March 
2010 meant that they were more likely to re-offend. Therefore, after controlling for offender characteristics the decrease was 2.3 percentage points. 

 
Among Youth Offending Teams (YOTs) re-offending rates varied considerably from 21.8 per cent to 48.7 per cent. A large part of this variability reflects the mix of offenders who are managed by different YOTs and therefore comparisons between YOTS should not be made using these raw reoffending rates.  
 
More information on youth criminal statistics is available at: www.justice.gov.uk/publications/statistics-and-data/youth-justice/statistics.htm 
 
Trends in proven re-offending across the country  
 
Map 1 shows proven re-offending rates by Upper Tier Local Authority. This chart is not controlled for the characteristics of offenders and is designed for users to gain an understanding of what the level of proven re-offending is in their area and how it is changing over time. When comparing between Local Authorities, the differences may be due to:  different types of offenders; areas where the offenders have high numbers of previous offences are likely to have higher proven re-offending rates 

 police activity; areas with high police detection rates are likely to have 
higher proven re-offending rates  
 age profile of offenders in the area; areas with a younger population are 
likely to have higher proven re-offending rates. 
 When comparing proven re-offending over time within Local Authorities, any significant changes in these factors may affect the comparison. Very few local authorities have shown substantial change compared to the same period last year. For local authorities with more than 100 offenders, the largest decrease was seen in Flintshire (3.2 percentage points) and the largest increase was in Monmouthshire (2.9 percentage points). (Table 13c) 

## Prolific And Priority Offenders (Ppo)

The Prolific and other Priority Offender Programme (PPO) aims to use a multiagency approach to focus on a very small but hard-core group of prolific/persistent offenders who commit a disproportionate amount of crime. Please refer to the Definitions and Measurement document for more detail: www.justice.gov.uk/publications/statistics-and-data/reoffending/provenreoffending-quarterly.htm Around 8,000 offenders (adult and juvenile) were on the PPO scheme at some point between April 2009 and March 20103. Of these just under 6,000 
committed a proven re-offence within a year (74.9 per cent). These offenders represented 1.2 per  cent of all offenders but were responsible for 5.6 per cent of all proven re-offences committed. Compared to the previous twelve months, the proportion of PPO offenders who committed a proven re-offence has decreased by 2.3 percentage points. 

This compares to an overall decrease of 2.1 percentage points since the scheme began in 2005. Drug Misusing Offenders (DMO) 
 
The Drug Interventions Programme (DIP) was introduced in April 2003 with the aim of developing and integrating measures for directing adult drugmisusing offenders into drug treatment and reducing offending behaviour. 

There are a number of ways offenders can be identified as drug misusers. Please refer to the Definitions and Measurement document for more detail: www.justice.gov.uk/publications/statistics-and-data/reoffending/provenreoffending-quarterly.htm 
 
Around 49,000 adult offenders were identified as drug misusers at some point between April 2009 and March 2010. Of these just over 27,000 committed a proven re-offence within a year (55.1 per cent). These offenders represented 8.7 percent of all adult offenders but were responsible for 26.8 per cent of all proven re-offences committed by adult offenders. 

 
Compared to the previous twelve months, the proportion of drug-misusing offenders who committed a proven re-offence fell slightly (0.5 percentage points).  Looking longer term there has been a decrease of 10.2 percentage points since 2005, although most of this change occurred between 2005 and 2006 when there was a large expansion in the drug intervention programme.

Annex A 
PAYMENT BY RESULTS Background 
 
The "Breaking the Cycle" Green Paper7 outlined the Ministry of Justice's commitment to commission at least six 'payment by results' (PbR) projects covering a significant proportion of the offender population. The MOJ intends to test the principle that PbR can result in service improvements, delivering better outcomes for the public at the same or less cost. In order to achieve this, the MOJ will pilot 'payment by results' at a number of prisons and local areas to test the concept and measure the results. The statistical "outcome" that MOJ is interested in is whether the PbR pilots can drive a real reduction in the proportion of offenders who are reconvicted 
(the re-conviction rate) in the 12 months following release from prison or from commencing a Court Order.   
 
Prison Results 
 
The re-conviction rate used for the PbR pilot prisons presented below differs from the National Statistics measure. It measures the proportion of offenders who are convicted at court in the 12 months following release from prison with a further six months to allow for cases to progress through the courts. This is because, for PbR purposes, we want to measure a change in the proportion of offenders who are convicted at court (whilst excluding those who receive an out-of-court disposal only) as court convictions are more closely associated with costs to the Criminal Justice System. Offenders are counted in the cohort if they are discharged from the prison at any time during the cohort year.  The measure excludes those who serve the whole of their custodial sentence on remand as well as the usual National Statistics exclusions as explained in the definitions and measurement document8. 

 
Table A1 below will be included in the Proven Re-offending quarterly bulletin each quarter and will include, for each pilot prison or area that uses the reconviction rate as its outcome measure, the baseline re-conviction rate, the target re-conviction rate9 and the outcome re-conviction rate. The only prison pilot included in Table A1 at present is HMP Doncaster, but this will be updated on an ongoing basis as new pilots begin and outturn results become available.

Notes: 
1. There is a PbR pilot ongoing at HMP Peterborough (the Peterborough 'Social Impact Bond').  This pilot uses a different outcome measure (the frequency of re-conviction events) and its success is measured against a control group. The results will be published separately. 
2. There is a Justice Reinvestment PbR pilot across five London boroughs and Greater 
Manchester, which use a different outcome measure, namely a reduction in demand on the CJS. The results will be published separately. 3. PbR pilots for offenders managed by the Probation Service are likely to begin in early 2013. When these are underway Table A1 will be updated to reflect these new PbR areas. 

## Annex B How The Measure Of Proven Re-Offending Has Changed And The Effect Of These Changes Background

The Ministry of Justice launched a statistical consultation on improvements to the transparency and accessibility of our information in 2010 and a response to the consultation was published in March 201110. One aspect of the consultation was the measurement of proven re-offending. Prior to the consultation there were six different measures of proven reoffending:  

 national adult proven re-offending;  local adult proven re-offending;  national youth proven re-offending;  local youth proven re-offending;  Prolific and other Priority Offending (PPO); and  drug-misusing proven offending. 
The new approach to measuring proven re-offending integrates these approaches into a single framework. This allows users to:  

 form a clear picture of proven re-offending at national and local levels;  compare adult and youth results, and enable other work on transition 
between the youth and adult criminal justice systems;  
 understand how results for different offender groups (such as those 
managed by the prison and probation services, those under the PPO 
schemes, drug-misusing offenders, first time entrants, etc) fit in to the 
overall picture on proven re-offending; and  
 continue to be able to analyse proven re-offending behaviour of 
particular types of offender. 

## Comparing Trends In Re-Offending

Table B1 shows the proportion of offenders with a proven re-offence/reconviction using the new measure of re-offending and the previous measures of adult re-conviction and juvenile re-offending. Comparisons we make use cohorts up to 2009. Re-offending rates are lower using the new measure than using the previous measure. The differences are as follows: 

 For adult and juvenile offenders the new measure is based on all 
offenders released from custody, receiving a non-custodial conviction 
                                                 
at court, a caution, reprimand, warning or tested positive for opiates or cocaine over a 12 month period, but the previous measures only included offenders released from custody or commencing a court order in the first three months of the year. Using a 3 month sample overrepresents prolific offenders in comparison to a full year's worth of data.   

 For adults the new measure counts all offenders including those who 
received a caution, fine or discharge, where the previous adult measure only included those who commenced a court order or were 
discharged from custody. 
 For adult offenders, the new measure is a measure of proven reoffending (which counts offences proven through a court conviction or 
a caution) whereas the previous measure is a measure of re-conviction (which only counts offences proven through a court conviction). 
As a result, re-offending rates are 14.4 percentage points lower for adults and rates for juveniles are 4.1 percentage points lower using the new measure. However, the re-offending rates are similar for adults given a court order or who received a custodial sentence, including those given a sentence of less than 12 months. Rates are between 1.0 and 2.6 percentage points lower using the new measure.

|----------------------------------------------------|----------------|-----------------------|
| Adults                                             |           24.9 |                  39.3 |
| Juveniles                                          |           32.8 |                  36.9 |
| Adults given a court order                         |           34.5 |                  35.5 |
| Adults given a custodial sentence                  |           46.8 |                  48.5 |
| Adults given a custodial sentence of less than 12m |           56.8 |                  59.4 |
|                                                    |                |                       |

 Figure B1 shows re-offending rates for adult offenders between 2000 and 2009 using the new and previous measure.  
 
In 2009 24.9 per cent of adult offenders have a proven re-offence within twelve months using the new measure compared to 39.3 per cent reconvicted using the previous measure. However, trends for adult offenders are similar using the two measures. The proportion of offenders with a proven re-offence/re-conviction rose between 2000 and 2002, fell between 2002 and 2006, rose between 2006 and 2008, and fell between 2008 and 2009 using both measures.  

The overall reduction in re-offending is smaller using the new measure (1.2 percentage points between 2000 and 2009 and 0.5 percentage points between 2008 and 2009) than using the previous measure (3.7 percentage points between 2000 and 2009 and 0.8 percentage points between 2008 and 2009).  
 
In 2009, 32.8 per cent of young offenders re-offended within twelve months using the new measure compared to 36.9 per cent using the previous measure. The reduction in re-offending is smaller using the new measure (0.9 percentage points between 2000 and 2009 and 0.1 percentage points between 2008 and 2009) than using the previous measure (3.3 percentage points between 2000 and 2009 and 0.4 percentage points between 2008 and 2009). Overall, the trends are broadly similar. 

 
Trends in proven re-offending/re-conviction rates for adult custodial offenders are similar using the new and previous measures. The proportion of offenders given a custodial sentence of less than 12 months who re-offended rose between 2000 and 2009 using both measures (by 2.6 percentage points using the new measure and 1.4 percentage points using the previous measure). The proportion of offenders given any custodial sentence who re-offended fell between 2000 and 2009 using both measures (by 2.6 percentage points using the new measure and 2.9 percentage points using the previous measure).

1. Based on the national adult re-convictions publication (March 2011) Among adult offenders in 2009, the previous national measure (the first column) shows that 39.3 per cent of adult offenders were re-convicted within a year based on a sample of 56,616 offenders. The second column shows the re-conviction rates from the previous measure looking at offenders who were released from custody or commenced a court order but at any point during the year. The inclusion of offenders from a full twelve month period means the results are calculated using the full proven offender population rather than a sample - this 
 
ensures we do not over-represent prolific offenders in the cohort, which is a problem in using a January to March sample as in the previous adult re-conviction measure. This leads to a lower proportion of re-convicted offenders (between three and five percentage points, eg 34.7 per cent compared to 39.3 per cent in 2009). The change to a full year also increases the number of offenders, to 200,077 in 200911. 

 
The third column shows the proven re-offending rates from the new measure but still based only on those offenders who were released from custody or commenced a court order at any point during the year. Proven re-offending includes offences which result in a caution in addition to those resulting in a conviction at court. The proportion of offenders who were proven to re-offend is between 1 and 2 percentage points higher than for those who were re-convicted (36.2 per cent compared to 34.7 per cent in 2009). There is little difference at this stage because we are still only considering offenders who already have a prison or a court order. The fourth column shows the re-offending rates from the new measure looking at all adult offenders who received a caution, a conviction at court, discharged from custody, or tested positive for cocaine or opiates. The inclusion of these offenders increases the numbers considerably.  In 2009, the previous adult measure tracks the re-offending behaviour of 
56,616 offenders; the new measure tracks 576,255 offenders. The inclusion of offenders who received less severe disposals and are generally less prolific in nature reduces the proportion who re-offend by around 11 to 16 percentage points (36.2 per cent compared to 24.9 per cent in 2009). 

Change over time Compared to the previous measure, the reduction over time in the proportion of offenders who re-offend is much lower using the new measure. Using the previous measure, between 2000 and 2009 the proportion of offenders who were re-convicted fell 3.7 percentage points (from 43.0 per cent to 39.3 per cent). Using the new measure, the proportion of offenders who committed a proven re-offence fell 1.2 percentage points (from 
26.2 per cent to 24.9 per cent).  
 
Juveniles The only change between the previous measure and the new measure of re-offending among young people is the move from a one quarter sample to including all young offenders over the period of a year.

1. Based on the national juvenile re-offending publication (March 2011) publication
 
As for adults, using the whole year reduces the proportion of offenders who re-offended because we do not over-represent prolific offenders in the cohort, which is a problem in using a January to March sample. Table B4 shows the reduction is between four and seven percentage points. For 2009 with the previous measure, 36.9 per cent commit a proven re-offence within one year; with the new measure, 32.8 per cent do so.  The new measure, which is based on offenders from a 12 month period, includes over three times as many offenders as the existing measure. Change over time Compared to the previous measure, the reduction in the proportion of offenders who reoffend between 2000 and 2009 is much lower using the new measure. Using the previous measure, between 2000 and 2009, the proportion of offenders who were proven to re-offend fell 3.3 percentage points (from 40.2 per cent to 36.9 per cent). 

Using the new measure, the proportion of offenders who committed a proven re-offence fell 0.9 percentage points (from 33.7 per cent to 32.8 per cent).  
 
Drug-misusing offenders Published results for drug-misusing offenders on the previous measure covered 2008 and 2009; results using the new measure cover from 2004 onwards.  
The previous measure: 

 Includes offenders who have been identified in the first quarter of the year, 
whereas the new measure includes offenders from any point during the year, 
 Includes all drug-misusing offenders irrespective of the date of proven offence, 
whereas the new measure includes identified drug-misusing offenders who have received a caution, been convicted at court, been discharged from custody, or tested positive for cocaine or opiates on arrest during a twelve month period. 
 Counts re-offences that were proven through a court conviction, whereas the new 
measure counts re-offences that were proven by a court conviction or caution.  
 As for adult and juvenile offenders, using the whole year to identify offenders reduces the proportion of offenders who re-offend, because we do not over-represent prolific offenders in the cohort, which is a problem in using a January to March sample. Table B5 shows the impact on reported rates of re-offending/re-conviction by drug-misusing offenders.

Table B5 shows that the proportion of offenders who commit a proven re-offence is between two and five percentage points lower using the new measure (57.0 per cent using the previous measure compared to 54.7 per cent using the new measure). The new measure, which follows offenders over a 12 month period, includes between two and three times as many offenders as the existing measure.  
 
Prolific and other Priority Offenders (PPO)  
Published results for PPOs on the previous measure presented the frequency of proven re-offending for all PPOs; results using the new measure cover the proportion of offenders proven to re-offend, and the frequency of proven re-offending for all offenders and for reoffenders from 2005 onwards. The previous measure:  

 Includes offenders who have been identified in the first quarter of the year, whereas 
the new measure includes offenders from any point during the year. However, PPOs are generally on the PPO programme for a sustained period of time so this only has a moderate impact on numbers of offenders included.  
 Includes all identified PPOs, whereas the new measure includes identified PPOs 
who have tested positive for cocaine or opiates, received a caution, been convicted at court, or been discharged from custody during a twelve-month period.  
 Counts re-offences that are proven through a court conviction or caution and also 
includes breach offences that lead to substantive recorded convictions. The new measure only includes re-offences proven through a court conviction or caution. 
 
Table B6 shows the impact on reported rates of proven re-offending by Prolific and other Priority Offenders and on numbers of offenders included in the measure.

1. Based on the national Prolific and other Priority Offenders publication (March 2010)

 The average number of proven re-offences committed by PPOs in 2009 is lower for the previous measure than for the new measure in 2008 (2.4 re-offences per offender using the previous measure, but 3.49 using the new). The previous measure includes PPOs who have not been proven guilty of an offence or been discharged from custody in the twelve month period when the re-offending cohort is formed. This type of offender is likely to have a lower level of re-offending. These differences may help to explain  

 why the frequency of re-offending is lower for the previous measure than for the 
new measure in 2009 (2.4 re-offences per offender using the previous measure, but 
3.49 using the new), and 
 why the previous measure includes nearly 2,500 more PPOs in 2009 than does the 
new measure.    

## Local Adult Re-Offending The Most Similar Results For The New Measure Of Re-Offending And The Existing Local Measure Of Adult Re-Offending Are The Early Estimates Of Re-Offending Of Offenders Given A Court Order. Like The Existing Measure Of Local Adult Re-Offending, The Early Estimates Of Offenders Given A Court Order:

 measure re-offending over three months,  only measures offenders under probation supervision,  provides results by probation trust, 
 
 compares actual re-offending rates with an predicted re-offending rate. There remain significant differences between the early estimates and the existing local adult measure of re-offending, including 

 The existing local adult measure includes offenders on license - the early 
estimates include offenders commencing court orders only. 
 The existing local adult measure uses a 'snapshot' approach. This means 
offenders are counted if they are on the caseload at certain times in the year. Offenders who are on the caseload for a short period of time may not get counted with the existing measure. The early estimates count every offender who commences a court order. 
 Because the existing local adult measure uses a 'snapshot' approach some 
offenders may get counted up to four times if they are on the caseload for over 
twelve months. The early estimates count every offender once. 
 The existing local adult measure measures the re-offending of offenders at any 
point during the court order - the early estimates measure re-offending in the first three months after an offender commenced a court order. 
 The predicted score for the existing local adult measure was derived from analysis 
of 2007 re-offending data - the prediction for the early estimates was derived from 
analysis of 2008 re-offending data.  
 These differences explain why the re-offending rate is higher with the early estimates of reoffending by offenders commencing a court order than with the existing measure of local adult re-offending:  

 offenders on license have lower rates of re-offending than those commencing a 
court order, and 
 offenders serving a court order have lower rates of re-offending the longer they are 
on that court order.  
However, the prediction for the early estimates has been tailored specifically to the relevant group of offenders. 

Local youth re-offending  
The previous measure of youth re-offending used data that Youth Offending Teams (YOT) collected themselves from their local police and courts. The measure was used as management information and was never published or put into the public domain. The new measure uses data from the Police National Computer (PNC). Internal analysis and discussion with stakeholders has highlighted a number of differences between the two data-sources: 

 The PNC includes a number of offenders who have received a reprimand or final 
warning which do not always appear on the YOT systems. As a result, there are 
more youth offenders and a higher overall youth re-offending rate using the new measure than using the previous local youth re-offending measure.  
 The PNC includes more comprehensive data on re-offending as adults by offenders 
who originally offended as youths.  
 Using PNC data reduces the data-collection burden on YOT and local police forces.  PNC data measures re-offending on recordable offences and YOT data measures 
re-offending on all offences. Offences which are not recordable include speeding 
offences, parking offences and other minor motoring offences. As a result, YOT 
data is more comprehensive for motoring re-offences.  
 The new measure allocates offenders to a locality using their home address data 
from the PNC; the previous local youth measure allocated offenders using offender 
management data. As a result, Looked After Children (LAC) who are in foster care, or in a children's home, or in a boarding school or live with another adult known to children's services, maybe allocated to a different YOT under the previous youth measure than the new measure.  
 For their re-offending to be included in the new measure, administrative data on 
young people in custody and secure accommodation has to be matched to the PNC. Some cases are not successfully matched. This process was not required for these offenders to be included in the previous local youth measure. As a result, YOT data can be more comprehensive regarding custodial offenders or those in 
secure accommodation.  
 Using PNC data provides an external measure of youth re-offending, which makes 
it an appropriate data-source to support any future policies which tie local funding to 
re-offending performance.  
 Using PNC data allows local youth re-offending to be measured on the same basis 
as national youth re-offending and adult re-offending, permitting adult and youth reoffending to be measured on a like-for-like basis and a more comprehensive picture of re-offending to be formed.  
 Work is underway to fully quantify the extent of these differences.   
 
   
 

## Annex C: Glossary Of Terms Re-Offending Terms

Cohort  - this is the group of individuals whose re-offending is measured.  
 
Index offence - the index offence is the proven offence that leads to an offender being included in the cohort. 

Index disposal - the index disposal of the offender is the type of sentence the offender received for their index offence. 

Start point (also known as the index date) - this is the set point in time from when reoffences are measured. 

Follow up period - this is the length of time proven re-offending is measured over.  
 
Waiting period - this is the additional time beyond the follow up period to allow for offences committed towards the end of the follow up period to be proved by a court conviction, caution, reprimand or final warning. 

Adjusted baseline - proven re-offending is related to the characteristics of offenders which means that any overall rate of proven re-offending will depend, in part, on the characteristics of offenders coming into the system (just as the examination pass rate of a school will be related to the characteristics of its pupils).  We use a modelling technique to produce a baseline figure adjusted to match the characteristics of the cohort we are comparing. For more details see the chapter on Statistical modelling and coefficients (p x) 
Reconviction - where an offender is convicted at court for an offence committed within a set follow up period and convicted within either the follow up period or waiting period 
 
Proven re-offence - where an offender is convicted at court or receives some other form of criminal justice sanction for an offence committed within a set follow up period and disposed of within either the follow up period or waiting period. 

## Cohort Defined Used In The Proven Re-Offending Statistic Quarterly Bulletin In England And Wales Publication

The proven re-offending cohort consists of all offenders discharged from custody, otherwise sanctioned at court, receiving a caution, reprimand or warning or tested positive for opiates or cocaine in each year.  This cohort's criminal history is collated and criminal behaviour is tracked over the following one year. Any offence committed in this one-year period which is proven by a court conviction or out-of-court disposal (either in the one-year period, or in a further six months waiting period) counts as a proven re-offence.

www.justice.gov.uk/publications/statistics-and-data/reoffending/juveniles.htm Disposals (Sentences) 

## Fine

A financial penalty imposed following conviction.  

## Court Orders

Court orders include community sentences, community orders and suspended sentence orders supervised by the Probation Service. They do not include any pre or post release supervision.  

## Criminal Justice Act 2003 (Cja03)

For offences committed on or after 4 April 2005, the new community order replaced all existing community sentences for adults. The Act also introduced a new suspended sentence order for offences which pass the custody threshold. It also changed the release 
 
arrangements for prisoners. See Appendix A of Offender Management Caseload Statistics96 for more information.  

## Community Order

For offences committed on or after 4 April 2005, the new community order introduced under the CJA 2003 replaced all existing community sentences for those aged 18 years and over. This term refers to all court orders except suspended sentence orders and deferred sentences which may have a custodial component to the sentence. The court must add at least one (but could potentially comprise of all 12) requirements depending on the offences and the offender. The requirements are:  

 unpaid work (formerly community service/community punishment) - a requirement 
to complete between 40 and 300 hours' unpaid work;  
 
 activity - for example, to attend basic skills classes;  
 
 programme - there are several designed to reduce the prospects of reoffending;  
 
 prohibited activity - a requirement not do so something that is likely to lead to 
further offender or nuisance;  
 
 curfew - which is electronically monitored;  
 
 exclusion - this is not used frequently as there is no reliable electronic monitoring 
yet available;  
 
 residence - requirement to reside only where approved by probation officer;  
 
 mental health treatment (requires offender's consent);  
 
 drug rehabilitation (requires offender's consent);  
 
 alcohol treatment (requires offender's consent);  
 
 supervision - meetings with probation officer to address needs/offending behaviour; 
and,  
 
 attendance centre - three hours of activity, between a minimum of 12 hours and a 
maximum of 36 in total.  
 Typically, the more serious the offence and the more extensive the offender's needs, the more requirements there will be. Most orders will comprise one or two requirements but there are packages of several requirements available where required. The court tailors the order as appropriate and is guided by the Probation Service through a pre-sentence report.  

## Suspended Sentence Order (Sso)

The Criminal Justice Act 2003 introduced a new suspended sentence order which is made up of the same requirements as a community order and, in the absence of breach is served wholly in the community supervised by the Probation Service. It consists of an 
'operational period' (the time for which the custodial sentence is suspended) and a 'supervision period' (the time during which any requirements take effect). Both may be 
 
between six months and two years and the 'supervision period' cannot be longer than the 
'operational period', although it may be shorter. Failure to comply with the requirements of the order or commission of another offence will almost certainly result in a custodial sentence.  
 

## Pre Cja03 Court Orders - Community Sentences:

Community punishment order (CPO): the offender is required to undertake unpaid 
community work. 
Community rehabilitation order (CRO): a community sentence which may have 
additional requirements such as residence, probation centre attendance or treatment for drug, alcohol or mental health problems. 
Community punishment and rehabilitation order (CPRO): a community sentence 
consisting of probation supervision alongside community punishment, with additional conditions like those of a community rehabilitation order. 
Drug treatment and testing order (DTTO): a community sentence targeted at offenders 
with drug misuse problems. 
Custody - the offender is awarded a sentence to be served in prison or YOI (Youth Offenders Institute). If the offender was given a sentence of 12 months or over, or was aged under 22 on release, the offender is supervised by the Probation Service on release. It is important to note that the sentence length awarded will be longer than the time served. For more information please refer to Appendix A of the Offender Management Caseload Statistics.  

## Prison Categories

Category B and Category C prisons hold sentenced prisoners of their respective categories, including life sentenced prisoners. The regime focuses on programmes that address offending behaviour and provide education, vocational training and purposeful work for prisoners who will normally spend several years in one prison.  
 
High Security Prisons hold Category A and B prisoners. Category A prisoners are managed by a process of dispersal, and these prisons also hold a proportion of Category B prisoners for whom they provide a similar regime to a Category B prison. The Category B prisoners held in a High Security Prison are not necessarily any more dangerous or difficult to manage than those in category B prisons. 

Female prisons. As the name implies, they hold women prisoners. Because of the smaller numbers, they are not divided into the same number of categories although there are variations in security levels. 

Local prisons serve the courts in the area. Historically their main function was to hold unconvicted and unsentenced prisoners and, once a prisoner had been sentenced, to allocate them on to a Category B, C or D prison as appropriate to serve their sentence. However, pressure on places means that many shorter term prisoners serve their entire sentence in a local prison, while longer term prisoners also complete some offending behaviour and training programmes there before moving on to lower security conditions. 

All local prisons operate to category B security standards.  
 
 
Open prisons have much lower levels of physical security and only hold Category D 
prisoners. Many prisoners in open prisons will be allowed to go out of the prison on a daily basis to take part in voluntary or paid work in the community in preparation for their approaching release. 

## Prisoner Categories

These categories are based on a combination of the type of crime committed, the length of sentence, the likelihood of escape, and the danger to the public if they did escape. The four categories are:  
 
Category A prisoners are those whose escape would be highly dangerous to the public or national security  
 
Category B prisoners are those who do not require maximum security, but for whom escape needs to be made very difficult Category C prisoners are those who cannot be trusted in open conditions but who are unlikely to try to escape Category D prisoners are those who can be reasonably trusted not to try to escape, and are given the privilege of an open prison. 

## Short Sentences - Under Twelve Months

Those sentenced to **under twelve months** (made under the Criminal Justice Act 1991) 
spend the first half of their sentence in prison and are then released and considered 'at risk' for the remaining period. This means they are under no positive obligations and do not report to the probation service but, if they commit a further imprisonable offence during the at risk period, they can be made to serve the remainder of the sentence in addition to the punishment for the new offence. The exception to this is those aged 18 to 20 who have a minimum of three months' supervision on release.  

## Sentences Of 12 Months Or Over

The Criminal Justice Act 2003 created a distinction between standard determinate sentences and **public protection sentences**. Offenders sentenced to a standard determinate sentence serve the first half in prison and the second half in the community on licence. 

## Reprimand Or Warnings

A reprimand is a formal verbal warning given by a police officer to a juvenile offender who admits they are guilty for a minor first offence. A final warning is similar to a reprimand, but can be used for either the first or second offence, and includes an assessment of the juvenile to determine the causes of their offending behaviour and a programme of activities is designed to address them. 

## First-Tier Penalties

Discharge - a juvenile offender is given an absolute discharge when they admit guilt, or are found guilty, with no further action taken. An offender given a conditional discharge 
 
also receives no immediate punishment, but is given a set period, during which if they commit a further offence, they can be brought back to court and re-sentenced.  

Fine - the size of the fine depends on the offence committed and the offender's financial 
circumstances. In the case of juveniles under 16, the fine is the responsibility of the offender's parent or carer. 
Referral order - this is given to juveniles pleading guilty and for whom it is their first time 
at court (unless the offence is so serious it merits a custodial sentence or it is of a relatively minor nature). The offender is required to attend a Youth Offender Panel to 
agree a contract, aimed to repair the harm caused by the offence and address the 
causes of the offending behaviour. 
Reparation order - the offender is required to repair the harm caused by their offence 
either directly to the victim or indirectly to the community. 

## Miscellaneous Terms Drug-Misusing Offenders

There are four ways a drug-misusing offender can be identified:  
Individuals who have tested positive for heroin or crack/cocaine following an arrest or 
charge for 'trigger' offences (largely acquisitive crime offences) as part of the Drug 
Interventions Programme (DIP) are included as adult proven offenders.  
  Any offender that received an OASys assessment whilst on licence or on a community 
sentence and are either recorded as being subject to a current Drug Treatment and 
Testing Order (DTTO) or Drug Rehabilitation Requirement (DRR), or are assessed as 
having a criminogenic drug need. 
  Any offender identified as requiring further drug interventions by Counselling, 
Assessment, Referral, Advice, Throughcare (CARAT) teams in prison, and now being released into the community. 
  Any offender identified by local Criminal Justice Integrated Teams (CJITs) as requiring 
further intervention for their drug use and offending as part of DIP. 

## National Probation Service

The National Probation Service generally deals with those aged 18 years and over. (Those under 18 are mostly dealt with by Youth Offending Teams, answering to the Youth Justice Board.) They are responsible for supervising offenders who are given community sentences and suspended sentence orders by the courts, as well as offenders given custodial sentences, both pre and post their release.  

## Police National Computer

The Police National Computer (PNC) is the police's administrative IT system used by all police forces in England and Wales and managed by the National Policing Improvement Agency. As with any large scale recording system the PNC is subject to possible errors with data entry and processing. The Ministry of Justice maintains a database based on weekly extracts of selected data from the PNC in order to compile statistics and conduct research on reoffending and criminal histories. The PNC largely covers recordable offences - these are all indictable and triable-either-way offences plus many of the more serious summary offences. All figures derived from the Ministry of Justice's PNC database, and in particular those for the most recent months, are likely to be revised as more information is recorded by the police.  

## Prolific And Other Priority Offenders

The Prolific and other Priority Offenders Programme (PPO) aims to use a multi-agency approach to focus on a very small but hard core group of prolific/persistent offenders who commit disproportionate amounts of crime and cause disproportionate harm to their local communities. The identification of a PPO is undertaken at a local level involving police, local authorities, prison and probation services and youth offending teams. The factors that influence the decision of whether an offender is included in the PPO programme are: 

 the nature and volume of crimes they commit;  the nature and volume of other harm they cause; and  the detrimental impact they have on their community. 

## Recordable Offences

Recordable offences are those that the police are required to record on the Police National Computer. They include all offences for which a custodial sentence can be given plus a range of other offences defined as recordable in legislation. They exclude a range of less serious summary offences, for example television licence evasion, driving without insurance, speeding and vehicle tax offences.  
Indictable and summary offences - Summary offences are triable only by a magistrates' 
court. This group includes motoring offences, common assault and criminal damage up to 
£5,000. More serious offences are classed either as **triable either way** (these can be tried either at the Crown Court or at a magistrates' court and include criminal damage where the value is £5,000 or greater, theft and burglary) or **indictable** (the most serious offences that must be tried at the Crown Court. These 'indictable-only' offences include murder, manslaughter, rape and robbery).  
 Offence Group - A split of offences into twelve separate groups. A more detailed split of the ten indictable offence groups (violence against the person, sexual offences, burglary, robbery, theft and handling and stolen goods, fraud and forgery, criminal damage, drug offences, other indictable offences (excluding motoring), indictable motoring) and the two summary offence groups (summary non-motoring and summary motoring offence types). 

  

Explanatory notes The United Kingdom Statistics Authority has designated these statistics as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics. Designation can be broadly interpreted to mean that the statistics: - meet identified user needs; - are well explained and readily accessible; - are produced according to sound methods, and - are managed impartially and objectively in the public interest. Once statistics have been designated as National Statistics it is a statutory requirement that the Code of Practice shall continue to be observed. The statistics in this bulletin relate to re-offending data in England and Wales. This is the first set of quarterly re-offending statistics to be published by the Ministry of Justice, subsuming a number of previous publications including: Adult re-convictions, juvenile reoffending, drug misusing offenders and prolific and priority offenders.
