Developing and requiring a new test for teacher-candidates is based on the belief that something is wrong with teacher preparation ("Performance-Based Test for Teachers Rolls Out," Dec. 4).
The evidence suggests the opposite is the case.
When we control for the effects of poverty, American students rank near the top of the world on international tests. Also, graduates of American schools go on to perform impressively in the real world: According to the 2013 Global Innovation Index, which is based partly on new patents and the publication of scientific and technical journal articles, the US economy ranks 5th in the world out of 142.
It is hard to conclude from these results that we have a problem in teacher education or teacher quality.
