The data of the Student Survey are available for scientific purposes via the Research Data Center (FDZ) of the German Center for Higher Education and Science Research (DZHW). Since December 1, 2021, a newly prepared multi-wave file is offered as SUF, which contains all data from the 13 surveys that were queried at least twice. This is accompanied by a detailed codebook, as well as extensive documentation and records. For the time being, the file is only available as a STATA file. The individual waves will be made available successively from January 2022.
