When I was the general counsel of the Los Angeles Unified School District, it was extraordinarily difficult to dismiss underperforming teachers who had tenure. One major problem was that we lacked objective measures of teacher effectiveness. So when the 2001 No Child Left Behind Act brought the nation annual standardized testing for math and reading, I applauded.
Congress is now seriously considering new legislation, the Every Child Achieves Act, which would continue the same testing program. But 14 years on, I think that's a mistake. I believe our exam system is deeply flawed, especially when it comes to teacher evaluation.
