📝PISA Education Score

PISA 2022 composite score — average of Mathematics, Reading, and Science (OECD Programme for International Student Assessment). Measures 15-year-olds' ability to apply knowledge to real-world problems, not rote memorization. Scores typically range 300–550. Top performers: Singapore 543 (2022 #1 globally), Japan 530, South Korea 527, Chinese Taipei 520, Hong Kong 520. Strong performers: Estonia 510, Ireland 504, Switzerland 508, Canada 517, Finland 516. Western European average: 470–490. Countries not participating in PISA (most of Africa, Central Asia, much of the Caribbean) are assigned estimated scores derived from UNESCO literacy data, expected years of schooling, and Human Capital Index — these are clearly indicative and should be interpreted with caution. The PISA score is weighted highest (25%) because it captures actual learned skill, not just input measures like spending or enrollment. Singapore's dominance reflects a system laser-focused on teacher quality, mastery learning, and curriculum depth.
