Progress is being made, says Childress, of the Gates Foundation, but at the rate even the most engaged school systems are improving, it will take 80 years to catch up to where China is now.

In 2008 the Stanford economist Eric Hanushek developed a new way to examine the link between a country’s GDP and the academic test scores of its children.
