The sample of the famous international PIAAC survey of adult skills did not include the institutionalised populations (incarcerated persons, people in military jobs, etc.). In 2014, the National Center for Education Statistics in collaboration with the US Department of Education and the Institute of Education Sciences undertook a separate survey based on the PIAAC methodology, which focused on comparison of skills of incarcerated adults compared to the general population.

The survey was designed to provide policy-makers, teachers and researchers with information that allows them to improve the learning and training opportunities of incarcerated adults and encourage skills they need for successful re-integration into society after the end of their sentence.

At the end of the survey, in 2016, the researchers published a report on key findings and conclusions on skills, work experience, education and training of incarcerated adults called Highlights from the U.S. PIAAC Survey of Incarcerated Adults: Their Skills, Work Experience, Education, and Training, which presents selected findings of the survey. You can read the report here.

We also invite you to read the summary of the key findings, which is published on the EPALE platform.
