U.S. Prison Study Data Collection

Prison data

The second round also included the U.S. PIAAC Prison Study, which was conducted from February through June 2014 to a sample of 1,270 adult inmates (ages 18–74) detained in federal and state prisons in the United States. The direct assessments of literacy, numeracy, and problem solving in technology-rich environments administered to adult inmates were the same as those administered to the U.S. PIAAC household participants. However, the household background questionnaire was modified and tailored specifically to address the experiences and needs of this subgroup. For example, the prison background questionnaire included items related to activities in prison, such as participation in academic programs and ESL classes; experiences with prison jobs; and involvement in nonacademic programs, such as employment readiness classes.
