Disrespecting professional judgment

Once again, Schools Matter has a thought provoking article.

Teachers can be replaced by tests they are not privy to and therefor cannot teach to.

Knowing this child has been thrown out of his house and is living with various friends, or this one is working to support his mother who lost her job - WHILE attending high school, or this one battles diabetes, or this one is doing the best she can with the hand she was dealt - know all that, the test can tell you more about what they have learned than I can?

Right.
