The 2nd COORDINATE Summer School was held at the Leibniz Institute for Educational Trajectories (LIfBi) in Bamberg, Germany, from July 10-14, 2023. The focus was on learning and applying specific methods for analyzing data from the German National Educational Panel Study (NEPS). Attendees got to know one of the most important panel data collections on educational and work trajectories, develop and advance their own research questions, and network with others who have similar research interests. The National Educational Panel Study (NEPS) is a large social science survey in the field of educational research. It follows a multicohort sequence design with six starting cohorts — newborns, kindergarten children, fifth graders, ninth graders, first-year students in higher education, adults — that were sampled through 2009 to 2012. Panel participants are regularly interviewed and tested over a period of more than ten years now. Relevant context persons such as parents, teachers or preschool staff are also included in the survey. Primary topics are (1) competence development, (2) learning environments, (3) social inequality and educational decisions, (4) migration background, (5) returns to education including satisfaction and wellbeing, (6) personality and motivation. Detailed biographical information complements the broad range of data.
