Data description

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:

  • Training/non-training enterprises
  • Participation in continuing vocational training
  • Planning and assessment of continuing vocational training
  • Costs of continuing vocational training courses
  • Time spent on continuing vocational training courses

For further information see CVTS implementation manuals (http://ec.europa.eu/eurostat/web/education-and-training/methodology).

Classification system

Classification of economic activities (NACE): NACE Rev. 1.1 up to 2005 and NACE Rev. 2 as from 2010.

Sector coverage

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:

  • planned training through guided-on-the-job training;
  • planned training through job rotation, exchanges, secondments or study visits;
  • planned training through participation (instruction received) in conferences, workshops, trade fairs and lectures;
  • planned training through participation in learning or quality circles;
  • planned training through self-directed learning/e-learning.

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:

  • fees and payments for CVT courses;
  • travel and subsistence payments related to CVT courses;
  • the labour costs of internal trainers for CVT courses (direct and indirect costs);
  • the costs for training centres, training rooms and teaching materials.

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.

Accuracy and reliability
Overall accuracy

The overall accuracy is considered as very good, significant variations had not been observed (see Sampling errors - indicators).

Sampling error

CVTS 5:

Sampling method

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.

Estimation/grossing-up procedures

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.

Non-sampling error

For survey 2010 response rate is 88.2%.

For survey 2015 response rate is 93.7%.

In variables B2 (B2a, B2b … etc.) the relative shares were replaced with absolute values, which were later transformed into percentages. No impact on the coherence.

There was an alternative for the enterprises to describe their economic activity instead of filling in the NACE code for A1. No impact on the coherence.

CVTS 4 and 5 questionnaire
 

No deviations from the European standard questionnaire.

 

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.

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.

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:

  • planned training through guided-on-the-job training;
  • planned training through job rotation, exchanges, secondments or study visits;
  • planned training through participation (instruction received) in conferences, workshops, trade fairs and lectures;
  • planned training through participation in learning or quality circles;
  • planned training through self-directed learning/e-learning.

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:

  • fees and payments for CVT courses;
  • travel and subsistence payments related to CVT courses;
  • the labour costs of internal trainers for CVT courses (direct and indirect costs);
  • the costs for training centres, training rooms and teaching materials.

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.
