This CD-ROM contains PISA 2015 restricted-use data for the United States. The CD-ROM includes the data file, a codebook, instructions on how to merge with the U.S. PISA 2015 public-use dataset (NCES 2017-120), and a cross-walk to assist in merging with other public datasets, such as the Common Core of Data (CCD) and Private School Survey (PSS). As these data files can be used to identify respondent schools, a restricted-use license must be obtained before access to the data is granted.
