The New York City schools have agreed to postpone releasing teacher value-added assessments to the public at least until legal hearings next month.
However, before that agreement was reached, Education Secretary Duncan weighed in supporting their release — sort of. It was clear he was supporting the School District, but it wasn’t quite clear exactly what he was supporting.
Duncan is just compounding what I believe to have been his biggest mistake since he became Secretary when he supported the LA Times decision to make teacher scores in that community public (see Why I Think Arne Duncan Has Just Made His Biggest Mistake).
