1 Introduction

Many countries in Europe have introduced training voucher programs to increase adults’ training participation that was set as a political aim on the European level. In December 2008, the training program „Bildungsprämie“ was implemented in Germany on the federal level. The main component of the program was a training voucher (Prämiengutschein) that reduced training costs by 50 percent up to a maximum subsidy of 500 Euro. Individuals eligible for the voucher include employees or self-employed with a maximum taxable income of 25,600 Euro for singles and 51,600 Euro for couples as well as individuals on maternity or parental leave. 1 In relation to all German employees, approximately two thirds of the German workforce was eligible for the voucher. In 2009, the Federal Ministry of Education and Research (BMBF) contracted the Rheinisch-Westfälisches Institut für Wirtschaftsforschung (RWI), the Gesellschaft für Innovationsforschung und Beratung (GIB Berlin) and the Institute for Applied Social Sciences (infas) to evaluate the effectiveness of this training program. 2

In this paper, we describe the data that was collected for the evaluation of the program. 3 Two different samples of individuals were surveyed by telephone: First, those individuals receiving a training voucher in 2010, henceforth referred to as voucher recipients, and, second, eligible employees. The first wave of the data was collected in 2010 and the second wave in 2011. To document potential changes in the composition of voucher recipients throughout the year 2010, the data was conducted in four cohorts covering information from the first to the fourth quarter. For reasons of comparability, the survey of eligible employees followed this cohort structure. For voucher recipients, a third wave on a largely reduced number of questions was carried out in June/July 2012. The survey on voucher recipients consists of 5,119 observations in the first wave. In the second and third wave, the number of observations was reduced to 2,210 and to 1,043 observations, respectively. The survey on eligible employees contains 6,075 observations in the first wave and 3,136 observations in the second wave.

The majority of questions are identical in both surveys: socio-demographics, the retrospective employment history, work-related characteristics, wages, education and training (including the characteristics of training). For voucher recipients, additional questions on their experiences with the voucher program were posed. For eligible employees, an experiment was implemented in the form of providing information on the voucher program to half of the randomly-chosen employees, while not providing this information to the other half.

Due to the manifold questions asked in the questionnaire, the data is suitable to investigate a variety of research questions for the group of low- and medium-income employees. In the following, we give some examples:

  • Training behavior (in particular, incidence and intensity as well as training characteristics including the monetary costs and the support by employers), reasons for non-participation, an assessment on the importance of lifelong learning and knowledge about educational and training programs in Germany;

  • Labor market status and dynamics;

  • Occupation, tasks, responsibilities and their changes across time;

  • Job satisfaction.

The remainder of this paper is organized as follows. The next two sections describe the sample design and implementation of the surveys for voucher recipients and eligible employees, respectively. In the fourth section, the contents of the questionnaires are described. Finally, information on data access is provided.

2 Voucher recipients

The target population of voucher recipients was defined based on the administrative records containing all voucher recipients. It covered all voucher recipients in 2010 for whom a voucher was issued in one of the four time periods: (i) from February to first week of March, (ii) April to first week of May, (iii) July and (iv) September to first week of October 2010. This cohort design was chosen (amongst other reasons) to conduct the interviews as shortly as possible after voucher receipt to observe individuals before voucher redemption and training participation (on average, interviews took place around 6 weeks after voucher receipt). In this population, telephone numbers had been provided for 80 percent during voucher application or could be recovered by telephone number search. Survey participants were drawn randomly from those voucher recipients for whom telephone numbers were available. In the first wave in 2010, 5,119 interviews could be conducted and the rate of response was very high (83 percent). One target of the first wave was to obtain information on voucher recipients’ experiences with the application process of the voucher and on their labor market status and job characteristics before participation in the voucher-financed training course. A detailed description of the content of the questionnaires can be found in section 4, separately by interview wave.

In 2011, the second interview was targeted at identifying changes in labor market outcomes occurring during the 12 months after initial contact. 4 For cost-efficiency reasons, the intended number of realized interviews was reduced to approximately 2,000 and the sample was stratified according to the status of voucher redemption at the time of the first interview. Specifically, recipients who had not redeemed their voucher at the time of the first interview were more likely to be surveyed in the second wave, while only a small number of recipients were sampled again who already had finished the voucher-financed training in the first wave. This was important for the evaluation design to estimate training returns which required information before and after course participation for persons who redeemed their voucher for training participation and for a control group of persons who were abstained from redeeming their voucher by an exogenous reason like course cancellation by the provider of training. 5 In the second wave (2011), 2,210 interviews could be realized successfully which relates to a response rate of 88 percent.

The third interview with voucher recipients was conducted in 2012 to identify changes in labor market outcomes occurring in the medium run, i. e. up to 24 months after training participation. Only persons were considered for the third interview who were interviewed successfully in the first two waves and who participated in cohorts (i) to (iii). The cohort design has not been followed in the third wave and all interviews were realized between June and July 2012. Again, the sample was stratified by status of voucher redemption, this time measured at the time of the second interview. For the evaluation, it was important to interview all persons again who did not redeem their voucher due to an exogenous reason until the third wave to keep the size of this control group as large as possible. Individuals who participated in a voucher-financed course according to their second wave interview were chosen randomly for the third wave. Persons not redeeming their voucher because of an endogenous reason were not considered at all. In the third wave, 1,043 voucher recipients were interviewed corresponding to a response rate of 84 percent.

3 Eligible employees

As already mentioned, the voucher is available for persons with low or medium household income if they are employed, self-employed or on maternity or parental leave. Since there is no single data set covering the universe of these individuals and for cost efficiency reasons, it was decided to primarily focus on eligible employees. 6 The sample was drawn from administrative records of the social security system covering all employees contributing to the social security system during the year 2008. Defining the target population from these records is not trivial, because taxable income depends e. g. on marital status, own individual income as well as partner’s income while the administrative records only include individuals’ labor income. Therefore, it was necessary to ask all relevant questions in the survey and then decide about eligibility during the interview. To keep the number of interviews with non-eligible employees as small as possible, individuals with low or medium labor income in the administrative records were sampled with a much higher probability than individuals with high labor income.

In the first wave in 2010, 6,075 employees could be interviewed (corresponding to a response rate of 35 percent) of whom 5,062 employees were identified as being eligible for the program. In the second wave, a reduced sample of randomly selected respondents, who had declared their agreement and were eligible for the program, were re-contacted. All in all, 3,136 interviews could be realized successfully which relates to a response rate of 71 percent.

In addition to collecting information on individuals’ personal, labor market and work characteristics, an experiment was implemented in the first interview. In the experiment, a random 50 percent of the eligible employees were informed about the general principle of the training voucher, its conditions and on how to obtain the voucher. 7 A detailed description of all contents of the questionnaires by survey wave can be found in section 4.
