And say it ain't so... again on RTTT

(Diane Ravitch on Race To The Top and evaluating teachers).

In all of these moves to evaluate students and teachers on the basis of testing, we assume that the tests are valid and the results reliable. This is a major assumption that needs to be explored. Fast.

My experience with testing students with disabilities and the use of accommodations and modifications concerns me greatly--as the use is often inconsistent and the validity of test results is assumed. Again, we need to explore this assumption. Fast.
