Jürgen Schupp

Project Period

July 1, 2013 - December 31, 2017

Commissioned by

BMBF (Federal Ministry of Education and Research)

In Cooperation With

GESIS - Leibniz Institute for the Social Sciences,
NEPS (National Educational Panel Study) at the LIfBi (Leibniz Institute for Educational Trajectories)

The Programme for the International Assessment of Adult Competencies (PIAAC), carried out on behalf of the OECD, examines the basic skills that are necessary for adults to participate successfully in society and working life. Findings from the 2011/2012 wave of the PIACC study were released in October 2013.

Around 98% of the approximately 5,400 PIAAC survey respondents in Germany agreed to participate in further surveys. PIAAC-L is a cooperative project of GESIS, the National Educational Panel Survey (NEPS) at the Leibniz Institute for Educational Trajectories (LIfBi), and the Socio-Economic Panel (SOEP) at DIW Berlin, whose aim is to convert the PIAAC study into a longitudinal study with three waves. This will create one of the world’s first internationally comparable longitudinal studies on competencies and their significance across the life course.

The project is planned to consist of three survey waves (in 2014, 2015, 2016) with different focal points. This will involve use of the SOEP core survey instruments (both individual and household questionnaires), PIAAC instruments (competency measurement and background questionnaire), and competency tests from NEPS and SOEP. In the first survey wave, only the SOEP survey instruments will be used (household and individual questionnaires). The third wave will focus on measuring the competencies of all household members based on the short scales used in the SOEP in 2006 and 2012 on basic cognitive skills. The surveys are aimed at comparative methodological analysis of the competency indicators used in PIAAC, NEPS, and SOEP and innovative analysis of labor market, education, and socio-political issues. By the end of the project, findings will be released on the influence of competencies on educational and professional careers in the form of research publications, and the data from all waves will have been made available to the research community together with supporting documentation. According to current plans, the analyses of competency related issues will make use of the longitudinal character of the new dataset and will be designed for comparison with the SOEP. It is also planned that as of 2018, participants from PIAAC-L who are willing to join a permanent, institutionalized longitudinal study will be transferred into either the recently launched SOEP Innovation Sample or the NEPS adult cohort.
