Proficiency in Key Information-Processing Skills among Working-Age Adults

This chapter gives an overview of the level and distribution of proficiency in key information-processing skills among the adult populations of countries participating in the Survey of Adult Skills (PIAAC). Results are presented separately for literacy, numeracy and problem solving in technology-rich environments. The presentation shows how adults are distributed across the different proficiency levels, the mean proficiency of adults, and the variations in proficiency across the population. To help readers interpret the findings, the results are linked to descriptions of what adults with particular scores can do.
