            COMMISSION REGULATION (EU) No 822/2010
of 17 September 2010
         
amending Regulation (EC) No 198/2006 implementing Regulation (EC) No 1552/2005 of the European Parliament and of the Council on statistics relating to vocational training in enterprises, as regards the data to be collected, the sampling, precision and quality requirements
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EC) No 1552/2005 of the European Parliament and of the Council of 7 September 2005 on statistics relating to vocational training in enterprises (1), and in particular Articles 7(3), 8(2) and 9(4) thereof,

Whereas:







(1)


Regulation (EC) No 1552/2005 establishes a common framework for the production of European statistics on vocational training in enterprises.












(2)


Commission Regulation (EC) No 198/2006 of 3 February 2006 implementing Regulation (EC) No 1552/2005 of the European Parliament and of the Council on statistics relating to vocational training in enterprises (2) defines the specific data to be collected with respect to the training and non-training enterprises and to the different forms of vocational training, the sampling and precision requirements, the quality requirements for the data to be collected, the structure of the quality reports.












(3)


Following the entry into force of Regulation (EC) No 1893/2006 of the European Parliament and of the Council of 20 December 2006 establishing the statistical classification of economic activities NACE Revision 2 (3), detailed NACE Rev.2 and size categories into which the results can be broken down should be adopted.












(4)


The Commission should define the specific data to be collected with respect to the training and non-training enterprises and to the different forms of vocational training.












(5)


Implementing measures concerning the quality requirements for the data to be collected and transmitted for European statistics on vocational training in enterprises, the structure of the quality reports and any measures necessary for assessing or improving the quality of the data should be adopted.












(6)


Regulation (EC) No 452/2008 of the European Parliament and of the Council of 23 April 2008 concerning the production and development of statistics on education and lifelong learning (4) defines a new statistical instrument on the participation of adults in lifelong learning.












(7)


In light of the information to be made available through Regulation (EC) No 452/2008 as well as of the need to improve the quality of the results on vocational training in enterprises and lower the statistical burden on enterprises, it is appropriate to modify the codification scheme, sampling, precision and quality requirements.












(8)


Regulation (EC) No 198/2006 should therefore be amended accordingly.












(9)


The measures provided for in this Regulation are in accordance with the opinion of the European Statistical System Committee,





HAS ADOPTED THIS REGULATION:



Article 1
Annexes I, II, III and V to Regulation (EC) No 198/2006 are replaced by the text set out in the Annex to this Regulation.

Imputation principles and record weighting

Countries shall take all appropriate measures to reduce item and unit non-response. Prior to imputation countries shall make all reasonable efforts to use other data sources.
Core variables, for which no missing value shall be accepted, nor imputation permitted are:






—


A1, A2tot, B1a, B1b, B2a(QL), B2b(QL) B2c(QL), B2d(QL) B2e(QL), F1tot.




Key variables, for which every effort should be made to avoid missing values and for which imputation is recommended are:






—


A3, A4, A5, C1tot, C3tot, C7sub, C7tot, PAC.




Imputation for item non-response shall be recommended within the following general limits:






1.


When a record contains less than 50 % of variables presented then this record shall normally be considered as a unit non-response.










2.


For a single NACE Rev.2/size cell imputations shall not be allowed if more than 50 % of the responding enterprises have missing data for more than 25 % of the quantitative variables.










3.


For a single NACE Rev.2/size cell, no imputation shall be performed on a quantitative variable if the proportion of responding enterprises for that particular variable is less than 50 %.










4.


For a single NACE Rev.2/size cell, no imputation shall be performed on a qualitative variable if the proportion of responding enterprises for that particular variable is less than 80 %.




Quantitative and qualitative variables are identified in Annex I.
Member States shall calculate and transmit a weight to be applied to each data record together with any auxiliary variables, which may have been used in the calculation of this weight. These auxiliary variables should be recorded as the variables RESPEXTRA1, RESPEXTRA2, RESPEXTRA3 as necessary. The methodology adopted for establishing the weights shall be detailed in the quality report.’;

This covers the type of results sent to enterprises, a dissemination scheme of results and a copy of any methodological documents relating to the statistics provided.
5.   COMPARABILITY
This covers the deviations from the standard European questionnaire and definitions provided in the manual referred to in Article 8 and a description of links done with other statistical sources (use of certain data available in registers, survey linked to another national survey).
6.   COHERENCE
This covers a comparison of statistics for the same phenomenon or item from other surveys or sources and an assessment of coherence with structural business statistics for the number of persons employed as a function of NACE Rev.2 and Size Group.
Tables to provide (broken down by NACE Rev.2 and size classes according to the national sampling plan, however allocation according to the observed enterprise characteristics):






—


Number of persons employed from structural business statistics and number of persons employed from CVTS.










—


Percentage of differences (SBS — CVTS)/SBS.




7.   COST AND BURDEN
This covers an analysis of the burden and benefit at national level through, for example, a consideration of average time for answering to each questionnaire, problematic questions and variables, variables most/least useful in describing CVT at national level, estimated or actual satisfaction level of data users at national level, difference of burden between for small and large enterprises and efforts made to reduce burden.



(2)  The coefficient of variation is the ratio of the square root of the variance of the estimator to the expected value. It is estimated by the ratio of the square root of the estimate of the sampling variance to the estimated value. The estimation of the sampling variance must take into account the sampling design and changes of strata."
