Useful for longitudinal analysis, cross country comparison, or teaching with real data. Includes mean scores by country, subject, and year for all seven PISA rounds.
A few notes for analysis: participation varies by round, sampling methodology has evolved, and several countries joined midway through the series. Scores are on a fixed scale calibrated to 2000 as baseline.
