The 2003 Program for International Student Assessment (PISA:03) is a study that is part of the Program for International Student Assessment (PISA) program; program data is available since 2000 at https://nces.ed.gov/pubsearch/getpubcats.asp?sid=098. PISA:03 (https://nces.ed.gov/surveys/pisa/) is a cross-sectional study that measures the yield of education systems, or what skills and competencies students have acquired and can apply in reading, mathematics, and science to real-world contexts by age 15. For PISA:03, mathematics literacy was the subject area assessed in-depth. The study was conducted using questionnaires and direct assessments of 15-year-old students. 15-year-old students in April to May of 2003 were sampled. The study's response rate was 83 percent. Key statistics produced from PISA:03 are 15-year-olds' capabilities in reading, mathematics, and science literacy.
