The Programme of the International Assessment of Adult Competencies (PIAAC) is an international assessment of the literacy, numeracy and problem solving skills of adults. The first cycle of the study involved three rounds of data collection involving a total of 39 countries and regions. Preparations for Cycle 2 of PIAAC started in 2018. As part of this process, the assessments of literacy, numeracy and problem solving have been redeveloped to reflect contemporary understandings of these skills and to make use of the opportunities offered by advances in testing technologies since Cycle 1 of the study. This document contains the frameworks that define and describe the skills assessed in Cycle 2 of PIAAC.

PIAAC is a collaboration between the countries participating in the study, the international contractor (a consortium led by Education Testing Service) responsible for the development of the study instruments, survey procedures, quality control and data preparation and the Organisation for Economic Co-operation and Development (OECD) responsible for the management of the project on behalf of participating countries.

The project is steered by the PIAAC Board of Participating Countries. Over the course of the development of Cycle 2 of PIAAC, the Board has been chaired by Ted Reininga (the Netherlands), together with Aviana Bulgarelli of Italy (until September 2020) and, from October 2020, Katalin Zoltán (Hungary).
