This report presents results of the Program for the International Assessment of Adult Competencies (PIAAC). Results are reported for a representative sample of adults in the United States age 16 to 65 and are compared to an international average of adults in countries/regions that participated in the PIAAC 2012 assessment. The report presents average score results for three separate scales: literacy, numeracy, and problem solving in technology-rich environments and percentages of adults performing at different proficiency levels for each scale. Literacy and numeracy results are reported at Below Level 1, Level 1, Level 2, Level 3, and Level 4/5; problem solving in technology-rich environments is reported at Below Level 1, Level 1, Level 2, and Level 3. The report includes results for groups of adults as defined by various demographic characteristics (e.g., gender, age, race/ethnicity, and level of educational attainment) and level of skill use in and outside of work. Overall results in literacy and numeracy are compared to results from previous international assessments.

NCES 98053 Adult Literacy in OECD Countries: Technical Report on the First International Adult Literacy Survey
This report has three objectives. First, the report attempts to document how the survey was conducted in each country and what was known at the time of the release of Literacy, Economy and Society about the extent of bias in each countries data. Second, the report includes the results of additional analyses which were undertaken to shed empirical light on the French concerns. These analyses are presented in the Appendices of the report. Thus, this volume should provide readers to draw their own informed conclusions about the quality of the data and the value of the study. Finally, the document serves the dual purpose of sensitizing countries considering participation in future rounds of IALS data collection about the need to adhere to the stated design specifications, and of informing the introduction of enhanced quality assurance procedures into the survey methodology. These enhancements will be documented in future editions of this report.
