The Program for International Student Assessment (PISA) is an international assessment that measures 15-year-old students' reading, mathematics, and science literacy. The PISA 2022 results represent outcomes from the 8th cycle of PISA since its inception in 2000. PISA has been conducted every 3 years except for a 1-year delay in the current cycle (from 2021 to 2022) due to the pandemic. After the 2025 data collection, PISA will change to a 4-year data collection cycle. The major domain of study rotates between mathematics, science, and reading in each cycle. PISA also includes measures of general or cross-curricular competencies, such as collaborative problem solving. By design, PISA emphasizes functional skills that students have acquired as they near the end of compulsory schooling. PISA is coordinated by the Organization for Economic Cooperation and Development (OECD), an intergovernmental organization of industrialized countries, and is conducted in the United States by NCES.Go to Overview to learn more about PISA.
