The Programme for the International Assessment of Adult Competencies (PIAAC) developed and conducts the Survey of Adult Skills. The survey measures adults’ proficiency in key information-processing skills - literacy, numeracy and problem solving in technology-rich environments - and gathers information and data on how adults use their skills at home, at work and in the wider community.
About the Survey of Adult Skills
This international survey is conducted in over 40 countries and measures the key cognitive and workplace skills needed for individuals to participate in society and for economies to prosper.
This website gives access to the log files from the PIAAC Study competency assessments on numeracy and problem solving in technology-rich environments. These log files offer new opportunities to researchers, for instance to reproduce test-taking behaviour of individuals and to better understand test-taking behaviour.
