Yong Zhao knows that American policymakers are obsessed with getting higher test scores.

Not their own test scores, of course, because they don’t take the tests, but the scores of America’s children.

We have only the scores of students in Shanghai, which are not representative of the nation.

Yong Zhao offers advice here on how to do it.
