The Program for International Student Assessment (PISA) is a system of international assessments that focuses on 15-year-olds' capabilities in reading literacy, mathematics literacy, and science literacy. It emphasizes functional skills that students have acquired as they near the end of mandatory schooling.
PISA is organized by the Organization for Economic Cooperation and Development, an intergovernmental organization of industrialized countries. Begun in 2000, PISA is administered every three years. AIR’s experts provide technical and analytical support for U.S. participation in PISA, including consultation and management support; support on survey and item development; technical review of statistical reports, data files and data documentation; expert analysis; technical support for the development of web-based data tools and other products; and training outside researchers to use PISA data files and other survey resources.
