Program for the International Assessment of Adult Competencies (PIAAC)
The Program for the International Assessment of Adult Competencies (PIAAC), also known as the Survey of Adult Skills, is a large-scale international study of key cognitive and workplace skills of adults.
Data is collected from adults ages 16–74 in the United States and ages 16–65 in the other countries.
It is designed to assess and compare adults’ skills in participating countries over a broad range of abilities, from reading simple passages to complex problem-solving skills, and to collect information on an individual's skill use and background.
