What this topic does not measure
How much children actually learn is only partly covered. International test scores exist for a limited group of countries, and they are published here as context rather than used as a key, because a key must describe most of the world. Universities, research, and youth and adult literacy also appear as context.
How the Education & Knowledge standing is decided
A standing is this site’s ordering, named with its edition — never a publisher’s rank. 4 key statistics vote, one vote each; every country’s published value becomes a place within that key’s own field, the places are averaged, and the average is never published. A country needs 2 of the 4 keys to be placed.
