The world's smartest countries in 2025 have been revealed, and Canada placed in the top 10.
Being a smart country is about how well nations learn, innovate, and apply knowledge.
This recent ranking from TradingPlatforms combined OECD PISA 2022 scores in math, science, and reading with scientific publication output and average IQ scores to create a global smartness ranking.
The analysis focuses on three key factors: student performance on the OECD’s 2022 PISA exams in math, reading, and science; the volume of scientific research papers published in 2024; and each country’s average IQ score.
These elements combine to form a comprehensive “Smartness Score,” which measures education, research output, and overall cognitive ability.
