Adults’ proficiency in key information-processing skills

This chapter describes the level and distribution of proficiency in the three information-processing skills assessed – literacy, numeracy and problem solving in technology-rich environments – among adults in the countries and economies participating in the Survey of Adult Skills. To help readers interpret the findings, it describes what the different levels of proficiency mean in concrete terms for each of these three domains. The chapter looks at the distribution in scores across countries and economies, and within participating countries, with particular focus on the six countries that participated in the third and final round of this cycle of data collection – Ecuador, Hungary, Kazakhstan, Mexico, Peru and the United States.
