The Continuing Vocational Training Survey (CVTS) collects information on enterprises’ investment in the continuing vocational training of their staff. Continuing vocational training (CVT) refers to education or training measures or activities which are financed in total or at least partly by the enterprise (directly or indirectly). Part financing could include the use of work-time for the training activity as well as financing of training equipment.
Information available from the CVTS is grouped around the following topics:
For further information see CVTS implementation manuals (http://ec.europa.eu/eurostat/web/education-and-training/methodology).
Classification of economic activities (NACE): NACE Rev. 1.1 up to 2005 and NACE Rev. 2 as from 2010.
CVTS covers enterprises with 10 or more employees belonging to the following sectors:
· For CVTS 4 (2010) and 5 (2015): to the NACE 2008 categories B, C (10-12, 13-15, 17-18, 19-23, 24-25, 26-28 and 33, 29-30, 16+31-32), D-E, F, G(45, 46, 47), I, H, J, K(64,65), K(66), L+M+N+R+S.
· For CVTS 2 (2000) and 3 (2005): to the NACE 2003 categories C, D (15-16, 17-19, 21-22, 23-26, 27-28, 29-33, 34-35, 20+36+37), E, F, G (50, 51, 52), H, I (60-63, 64), J (65-66, 67), K+O.
|Statistical concepts and definitions|
Continuing vocational training (CVT) are training measures or activities which have as their primary objectives the acquisition of new competences or the development and improvement of existing ones and which must be financed at least partly by the enterprises for their persons employed who either have a working contract or who benefit directly from their work for the enterprise such as unpaid family workers and casual workers. Persons employed holding an apprenticeship or training contract should not be taken into consideration for CVT. The training measures or activities must be planned in advance and must be organised or supported with the special goal of learning. Random learning and initial vocational training (IVT) are explicitly excluded. CVT measures and activities cover both CVT courses and other forms of CVT.
CVT courses are typically clearly separated from the active workplace (learning takes place in locations specially assigned for learning like a class room or training centre). They show a high degree of organisation (time, space and content) by a trainer or a training institution. The content is designed for a group of learners (e.g. a curriculum exists). Two distinct types of CVT courses are identified: internal and external CVT courses.
Other forms of CVT are typically connected to the active work and the active workplace, but they can also include participation (instruction) in conferences, trade fairs etc. for the purpose of learning. These other forms of CVT are often characterised by a degree of self-organisation (time, space and content) by the individual learner or by a group of learners. The content is often tailored according to the learners’ individual needs in the workplace. The following types of other forms of CVT are identified:
Training enterprises are enterprises that provided CVT courses or other forms of CVT for their persons employed during the reference year.
A participant in CVT courses is a person who has taken part in one or more CVT courses during the reference year. Each person should be counted only once, irrespective of the number of CVT courses he or she has participated in. E.g. if a person employed has participated in two externally managed courses and one internally managed course, he or she should be counted as one participant.
The costs of CVT courses cover direct costs, participants’ labour costs and the balance of contributions (net contribution) to and receipts from training funds.
Direct course costs:
Participants’ labour costs (personal absence costs) refer to the labour costs of participants for CVT courses that take place during paid working time.
Time spent on CVT courses refers to paid working time (in hours) spent on CVT courses, i.e. the time that all participants have spent in total during the reference year.
Since 2005, the CVTS contains some variables on initial vocational training (IVT). IVT within enterprises is defined as a formal education programme (or a component of it) where working time alternates between periods of practical training (workplace) and general/theoretical education (educational institution/training centre). The definition of IVT differs between CVTS waves, for details see the implementation manuals for each wave, available in CIRCABC.
The number of persons employed is defined as the total number of persons who work in the observation unit excluding persons employed holding an apprenticeship or training contract (i.e. the definition of persons employed in CVTS deviates from the one used for structural business statistics as regards the treatment of persons employed holding an apprenticeship or training contract).
For additional definitions used in CVTS and further information see the CVTS implementation manuals available in CIRCABC.
Enterprises with 10 or more persons employed belonging to certain NACE categories.

|Confidentiality - policy|
· Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.
|Confidentiality - data treatment|
Data are disseminated in aggregated form. Due to confidentiality issues data are presented for groups of NACE and enterprise size classes. Estimates are systematically based on at least three enterprises; where necessary, additional restrictions are applied.
In accordance to the dates defined in the Release Calendar presenting the results of the statistical surveys carried out by the National Statistical Institute.

|Documentation on methodology|
For each wave of the CVTS a detailed implementation manual is available which contains definitions and additional methodological explanations, a European standard questionnaire and the code book.
The implementation manuals are available in CIRCABC.
CVTS 3: the EU quality report is available in CIRCABC.
CVTS 4: the EU quality report as well as national quality reports are available in CIRCABC.
CVTS 5: to be announced.
A set of quality criteria have been set up within the CVTS legislation (see Legal acts and other agreements).
Statistics based on the CVTS are considered to be of satisfactory quality thanks to a harmonised production process (see Legal acts and other agreements). The CVTS is a sample survey and thus the results are subject to the usual statistical errors of measurement. Some issues arise from non-response.
Data are used by:
Commission (DGs, Secretariat General), Council, European Parliament, other European Agencies
Not surveyed yet.
Dataset covers all NACE sectors, enterprise size groups and variables as requested in the gentlemen’s agreement (CVTS 2) and in legislation (CVTS 3, 4 and 5) (http://ec.europa.eu/eurostat/web/education-and-training/legislation).
|Accuracy and reliability|
The overall accuracy is considered as very good, significant variations had not been observed (see Sampling errors - indicators).
Business register as of 31.12.2014 was used as a sampling frame. The sample was stratified by NACE Rev.2 (20 categories: B, C10-C12 ,C13-C15 ,C17-C18 ,C19-C23 ,C24-C25, C26-C28 and C33, C29-C30, C16+C31-32, D-E, F, G(45), G(46), G(47), I, H, J, K(64,65), K(66), L+M+N+R+S) and 3 size category (based on the number of employed). All sampling procedures were in accordance to the Commission Regulation No 1153/2014.
The current business register data as of 31 December 2015 for the total population was used for weighting and adjustment of the results.
The data obtained by the survey was post-stratified. The total number of poststrata was 140 (20 NACE categories used for sampling and 7 size groups (based on the number of employed).
Calculation of the coefficients of variation
All calculations of the standard errors and coeficients of variation were performed by SPSS (PASW) software, Complex Sample Analysis Module.
More information about CVTS 4's sampling method and errors could be found on CIRCABC.
For survey 2010 response rate is 88.2%.
For survey 2015 response rate is 93.7%.
For more detailed information see ‘Coverage error’ section.
|Timeliness and punctuality|
All deliverables were sent on time.
|Coherence and comparability|
|Comparability - geographical|
|Comparability - over time|
Partially comparable due to the changes of the general methodology and the economic activities of the surveyed enterprises. Modifications have actually been made in view of improving the overall quality of CVTS and are not considered to have a serious impact on the comparability.
|Coherence - cross domain|
CVTS data has been compared with Structural Business Statistics data with regard to number of persons employed. Full comparability is not possible due to differences in methodology.
|Coherence - internal|
CVTS results for a given reference year are based on the same microdata and results are calculated using the same estimation methods, therefore the data are internally coherent.
|Cost and burden|
Staff involved in administering survey:
4 experts from Department ‘Education and Culture statistics’ – responsible for survey organization, implementation of methodology, preparation of the national questionnaire, sampling, data processing, preparation of EU dataset and quality report, data dissemination;
1 expert from Department ‘Information and Application Software’ – responsible for preparation of informatics tool.
|Data revision - policy|
In accordance to the interior (for the NSI) rules for data dissemination.
|Data revision - practice|
In accordance to the interior (for the NSI) rules for data dissemination.
CVTS data are produced by the National Statistical Institute. The sampling frame used is the National Statistical Business Register (SBR), which is considered of good quality (coverage, regular updates, etc.). The sample is stratified by NACE and size classes; sampling requirements for CVTS are set in the relevant legislation documents. Survey participation for the enterprises was mandatory.
|Frequency of data collection|
Every 5 years.
CVTS was a stand-alone survey.
CVTS 4: Face-to-face (PAPI) and postal.
CVTS 5: Self-administered interview - paper assisted (PAPI, includes electronically submitted PDF version of the questionnaire) and Self-administered interview - computer assisted (CAWI with interactive online questionnaire).
Pilot test of the CVTS questionnaires was partly implemented.
The data tools framework (application for data entry) was designed with additional controls and filters. There were added also extra checking rules by comparing the entered information between different related questions in order to confront possible inconsistent answers. Finally the data checking tool (EDIT) provided by Eurostat had been used for the data set checks. No major errors detected.
