I just read this piece about needing a New Deal for testing… and add my voice to the conversation.
Using student test results to measure teacher performance is not just ‘starting to damage our schools.’ It is flawed in a far more basic way–it is invalid use of those tests. These tests are designed to measure student performance against the Common Core–and to assess college and career readiness. They are NOT designed to measure teachers. I’m afraid that using them for this invalid purpose (no matter how carefully the statistical model may be) invites litigation and further erodes support for education reform.
