IDSR data amendment

We have identified and corrected an error relating to the calculation of the ‘High - low prior attainers’ flag in the Year group context field within the tables in the Achievement at key stage 4 section of the IDSR. For a subset of schools, this meant they received the flag where they should not have or did not receive the flag where they should. It did not affect the achievement data or any of the other analysis of it, including the other Year group context flags. This has now been corrected for all IDSRs containing key stage 4 data as of today’s release.

If you have any questions or concerns with any of the above, please email the team at: xxx@xxx.xx (mailto:xxx@xxx.xx).

For further information about the new IDSR and the renewed framework, read our blogs:
- Our renewed inspection framework: what we’ve learned from pilots (https://educationinspection.blog.gov.uk/2025/11/05/our-renewed-inspection-framework-what-weve-learned-from-pilots/)
- The role of data on school and further education inspections (https://educationinspection.blog.gov.uk/2025/11/07/the-role-of-data-on-school-and-further-education-inspections/)
Furthermore, there is a link to register for an Ofsted webinar for schools (https://register.gotowebinar.com/register/1760335059574989660).

This webinar will provide schools with information about the new achievement evaluation area and how Ofsted uses data, including an overview of the new-style Inspection Data Summary Report (IDSR). In particular, the webinar will:
- share details about the achievement evaluation area and its use on school inspection
- provide a brief overview of what has changed in the IDSR and how our inspectors will use data on inspection
- answer your questions
Our next planned release is scheduled for early to mid-December. Please sign up for email alerts for this page so you never miss an update.

Please note, Ofsted has now received the delayed provisional key stage 4 and 16 to 18 performance data from the Department for Education. We will release this data in January 2025.

IDSR update: 12 November 2024

The Department for Education has informed us that there are delays to the publishing of provisional 2023/24 key stage 4 and 16 to 18 performance data.

Key stage 4 provisional subject entries, attainment and progress data and 16 to 18 data for 2024 have been delayed due to quality issues in data submitted to the Department for Education by an awarding organisation. These were identified in the ‘Check Your Performance Measures Data’ exercise. A new publication date will be announced as soon as possible in line with the requirements of the Code of Practice for Statistics.

Due to these delays the secondary and all-through school IDSRs will not be updated in November with provisional key stage 4 and 16 to 18 data, as per previous years. We plan to update them in January, providing there are no further delays in receiving the data.

IDSR data correction

We have identified and corrected an error relating to a small number of calculations that interpret Attainment 8 measures within the IDSR. For a subset of schools, this affected the arrows and/or the significance for Attainment 8 measures displayed in the ‘Progress and attainment at key stage 4’ section. It also sometimes affected the ‘Pupil groups’ section for Attainment 8 measures . It did not affect the Attainment 8 scores, cohorts or percentiles. This has now been corrected for all IDSRs containing key stage 4 data which now have a release date of 11 November.

If you have any questions or concerns with any of the above, please email the team at: xxx@xxx.xx (mailto:xxx@xxx.xx)

We have also made changes to the way we calculate key stage 4 subject entries so that they align with ‘Find school and college performance’ (https://www.find-school-performance-data.service.gov.uk/).

IDSR release: 8 February 2023

We have updated the inspection data summary report (IDSR) for primary schools.

The following data has been updated:
- Key stage 2 - revised
- Key stage 1 - final
- phonics - final
We have also made minor changes to the pupil movement section of the secondary school IDSR.

IDSR release: 10 January 2023

We have updated the IDSR for schools with key stage 4. The update is a correction to the EBacc science, languages and humanities attainment sentences within the key stage 4 subjects section of the areas of interest. This was due to a methodology issue with the calculation of the highest and lowest 20%. This has not impacted all of these schools.

The correction may result in the EBacc attainment sentences changing. For example, the sentence for the school may now be shown in grey when previously it was highlighted as in the highest or lowest 20%. Quality checks have been conducted to ensure this does not affect other sentences.

2022 IDSR releases

IDSR release: 15 December 2022

We have released the December 2022 inspection data summary report (IDSR) for all schools.

The following data has been updated:
- absence data for 2021/22 (autumn and spring terms)
Pupil movement section

The text relating to pupils for whom we do not have information about in the later census has been improved. This change was made based on feedback we received. Our guidance has additional text to convey that the school may well have information about these pupil who may, for example, have moved overseas. Examples of the existing and new sentences are below.

Older sentenceThere is no available information about the destinations of 50 of these 75 pupil(s), 11 of whom left between Years 10 and 11.

New sentenceThere is no recorded information in the January 2021 census for 50 of these 75 pupil(s), 11 of whom left between Years 10 and 11.

Trust/LA level information section

The heading for this section dynamic so that if will display as either ‘Trust information’ or ‘LA information’ dependent on school type.

For multi-academy trusts only, overall effectiveness grades based on the latest URN will appear in this section. This will mean that grades associated with a school prior to joining the MAT will now not appear in the grade profile, instead they will appear in the ‘not yet inspected’ section.

Comparisons should not be made with data from earlier years. As always, inspection judgements will not be based on data and evidence alone. Ofsted will use this data with caution and take the COVID-19 context into account when forming a rounded judgement about a school.

IDSR release: 6 June 2022

Removal of early years foundation stage (EYFS) data

We have updated the inspection data summary report (IDSR) with absence data from summer term 2021, based on the DfE published data. We have not included spring 2021 in the IDSR as this was heavily affected by the lockdown from 4 January 2021.
