Every three years, the Organisation for Economic Co-operation and Development (OECD) administers the PISA exam—the world's most comprehensive assessment of student achievement across 80+ countries.
And every three years, the same pattern emerges: Singapore, Japan, South Korea, and China dominate the top rankings in reading, writing, and literacy.
The United States? Consistently middle-of-the-pack. In the most recent assessment, American students ranked 13th in reading—behind not just Asian nations, but Estonia, Canada, and Ireland.
For years, Western educators have tried to explain this gap with cultural factors: "Asian students study more," or "Asian parents push harder." But a growing body of research points to something far more specific—a fundamental difference in how writing and literacy are taught.
