The Skills Map provides policymakers, business leaders, educators, and researchers access to data that will support economic development, inform policy solutions, and improve education. The PIAAC Skills Map was recently released by the National Center for Education Statistics (NCES). The PIAAC Skills Map is an interactive tool that presents state and county estimates of adult literacy and numeracy proficiency. These new data include first-of-their kind state- and county-level data on numeracy skills, and greater detail about literacy skills at the state and county level. Tom Krenzke, the key expert of the Skills Map, is a Vice President and a Senior Statistician in Westat’s Statistics and Evaluation Sciences Unit. He is the director of sampling activities for PIAAC in the US, and is Senior Lead Statistician within the PIAAC International Consortium. He has over 25 years of experience in statistical research and software development, including emphasis on sample design for household surveys, and small area estimation. Mr. Krenzke is a Fellow of the American Statistical Association (ASA), Chair of the ASA Committee on Privacy and Confidentiality, and Past-president of the Washington Statistical Society.

RISE Webinar: PIAAC Skills Map: Implications for Research, Policy and Practice

On Wednesday, August 26, 2020, AIR hosted a demonstration of the U.S. PIAAC Skills Map: State and County Indicators of Adult Literacy and Numeracy, a new interactive data tool recently released by the National Center for Education Statistics (NCES). The discussion covered the potential uses of the data from a policy and research perspective, which relates to the workforce, adult basic education, and training.

The Skills Map provides easy access to new information about the literacy and numeracy proficiency of adults ages 16-74 in all 50 states, the District of Columbia, and all 3,141 counties across the United States as well as the ability to view side-by-side comparisons of performance for individual states and counties.

According to recent PIAAC data, roughly 1 in 5 U.S. adults lacks basic literacy skills, while nearly 1 in 3 lacks basic numeracy skills. The demonstration reviewed average scores and the proportion of adults performing at each proficiency level (lowest, middle, and highest performers). Users can access selected state- and county-level demographic information such as educational attainment, race/ethnicity, employment status, and poverty level, to better understand the results produced for each state or county.
