The PIAAC U.S. RUF 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. In addition to the variables in the PUF (NCES 2014-045REV), the RUF contains detailed versions of variables and additional data collected through U.S. specific questionnaire routing. The RUF can be accessed through a restricted use license agreement with the National Center for Education Statistics. For more details on the RUF, please refer to Appendix J of the U.S. PIAAC Technical Report (NCES 2014-047).

Important note to users:

These original 2012 data have been updated, reweighted, and revised with the release of the PIAAC 2012/2014 restricted-use dataset (NCES 2016-668). That dataset should be used for analyses instead of this original version unless you are seeking to reproduce historic analyses.

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: holly.xie@ed.gov.

NCEE 20124015 Whether and How to Use State Tests to Measure Student Achievement in a Multi-State Randomized Experiment: An Empirical Assessment Based on Four Recent Evaluations
An important question for educational evaluators is how best to measure academic achievement, the outcome of primary interest in many studies. In large-scale evaluations, student achievement has typically been measured by administering a common standardized test to all students in the study (a “study-administered test”). In the era of No Child Left Behind (NCLB), however, state assessments have become an increasingly viable source of information on student achievement. Using state tests scores can yield substantial cost savings for the study and can eliminate the burden of additional testing on students and teaching staff. On the other hand, state tests can also pose certain difficulties: their content may not be well aligned with the outcomes targeted by the intervention and variation in the content and scale of the tests can complicate pooling scores across states and grades.

This NCEE Reference Report, Whether and How to Use State Tests to Measure Student Achievement in a Multi-State Randomized Experiment: An Empirical Assessment Based on Four Recent Evaluations, examines the sensitivity of impact findings to (1) the type of assessment used to measure achievement (state tests or a study-administered test); and (2) analytical decisions about how to pool state test data across states and grades. These questions are examined using data from four recent IES-funded experimental design studies that measured student achievement using both state tests and a study-administered test. Each study spans multiple states and two of the studies span several grade levels.
