PISA is an international evaluation by the OECD that tests 15-year-old students in reading, math, and science every three years. It compares educational systems across countries.

Strengths:

• Provides global benchmarks for student achievement.
• Highlights strengths and weaknesses in national education systems.
• Encourages policymakers to improve curricula and teaching methods.

Weaknesses:

• Focuses mainly on test-based knowledge, overlooking creativity and socio-emotional skills.
• Cultural and language differences may affect fairness.
• Can lead to “teaching to the test” instead of fostering deeper learning.
