The Los Angeles Times became notorious in 2010 when it commissioned its own ratings of thousands of teachers in the LAUSD and published them. The newspaper was condemned widely by educators and researchers. Even some who supported such ratings said it was wrong to publish them. The LA Times strongly defended its decision to create the ratings and to make them public.

Now the LA Times is expressing doubts about the overuse of test scores to evaluate teachers. It even scoffs at some of the more absurd practices now flourishing in some states.

Why the turnaround? Bill Gates says that test scores matter too much. He has changed his mind. Many states, following his earlier views about testing, are emphasizing test scores too much.

I guess we have to wait for his next op-ed to find out what the nation should do next.
