Program for the International Assessment of Adult Competencies (PIAAC) 2012: U.S. Main Study Technical Report is a technical manual that describes how these data were collected and processed as well as how to use the data files to conduct statistical analyses. Information is presented on meeting PIAAC consortium requirements, sample design, listing of dwelling units, data collection, reducing the risk of data disclosure, the need for conducting a nonresponse bias analysis, weighting and variance estimation, and data preparation and processing. The appendices of the Technical Report include background questionnaire adaptations, data collection reports, interviewer training reports, outreach materials, interviewer debriefing report, basic analysis tables, extended analysis tables, weighted item response rates, technical notes, and data user guidance.
Important note to users:
These original 2012 data have been updated, reweighted, and revised with the release of the
PIAAC 2012/2014: Main Study and National Supplement Technical Report (NCES-2016-036). That dataset should be used for analyses instead of this original version unless you are seeking to reproduce historic analyses.
