The Research Data Center LIfBi (Forschungsdatenzentrum, FDZ-LIfBi) is primarily responsible for the user-friendly preparation of survey and test data of the National Educational Panel Study (NEPS) and its cost-free dissemination to researchers in the form of Scientific Use Files. Also data from other projects such as ReGES are hosted by the FDZ-LIfBi. The necessary processes of data editing range from checking incoming data packages, integrating them into standardized data formats, coding open entries, generating additional variables and data sets, anonymizing sensitive content, and linking of the data with appropriate metadata.  The FDZ-LIfBi also provides comprehensive documentation of the data material in German and English and ensures secure and flexible data access via several options (download, remote, on-site).
