In July 2023, a total of 31 researchers from 14 countries met for one week at the Leibniz Institute for Educational Trajectories (LIfBi) for the 2nd COORDINATE Summer School. Organized by the Research Data Center (FDZ-LIfBi), the event focused on learning special analysis techniques for evaluating, in particular, the competency and episodic data of the National Education Panel Study (NEPS). In addition to an introduction to the framework concept of the NEPS study and the structure of the scientific-use files, the program included a series of guided exercises on data preparation and analysis as well as a presentation on sequence data analysis. The program concluded with a presentation of the research ideas developed during the week.
