GESIS, LIfBi, and DIW are together conducting one of the world's first internationally comparable long-term studies on adult competencies and their significance over the life course.


How do individual competencies impact on the employment careers of people living in Germany? How are person abilities interrelated with occupational mobility? How are competencies distributed between individual families and between partners? And what does this mean for chances of upward mobility in our society?

These and similar questions are examined by the nationwide long-term study PIAAC-L, for which funding worth over €5.7 million is provided by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF). PIAAC-L continues the work of PIAAC in a German context. PIAAC—a study by the OECD and also known as the PISA study for adults—analyzed everyday skills and abilities of adults by international comparison.

The study is carried out by researchers from the Leibniz-Institute for the Social Sciences GESIS, the Leibniz Institute for Educational Trajectories LIfBi, and the German Socio-Economic Panel SOEP situated at the German Institute for Economic Research (DIW Berlin) (see all members of the consortium). About 5,000 people in Germany aged between 18 and 67 years who have participated in PIAAC before, as well as their families, are surveyed by PIAAC-L. Overall, the survey will take place in three waves from 2014 through 2017.
