Title: Program for the International Assessment of Adult Competencies (PIAAC) 2012 U.S. Public Use File (PUF)
Description: The PIAAC U.S. PUF contains individual unit record data including both responses to the background questionnaire and the cognitive assessment from the original U.S. PIAAC data collection completed in 2012. Statistical disclosure control treatments were applied due to confidentiality concerns. For more details on the PUF, please refer to Appendix J of the U.S. PIAAC Technical Report (NCES 2014-047).

Important notes to users:
  1. These original 2012 data have been updated, reweighted, and revised with the release of the PIAAC 2012/2014 dataset (NCES 2016-667). That dataset should be used for analyses instead of this original version unless you are seeking to reproduce historic analyses.
  2. The OECD identified an error in the derivation of the following variables in the PIAAC original 2012 data files: NFE12JR, NFE12NJR, FNFE12JR, FNFAET12JR and FNFAET12NJR. NCES released revised U.S. public-use and restricted-use files, the background compendia, and the codebook on August 18, 2015. The revised public-use files are available below. IDE (International Data Explorer) was updated with the revised datafile on March 27, 2015. If you have any questions, please contact:
