The Research Data Center PIAAC (RDC PIAAC) informs on this website about the current PIAAC datasets. To download PIAAC data via the GESIS Data Catalogue (DBK), ordinarily a registration (Registration) and signing a data distribution contract is required. Several documents such as variable reports and questionnaires are available without registration. Furthermore, we offer PIAAC data users the possibility to work with more sensitive data (e.g., regional data) at our GESIS Secure Data Center (SDC).
