Reblogged from Diane Ravitch's blog:
As we saw in the previous postTom Sgouros explained in detail why it was wrong for Rhode Island to use the NECAP as a graduation requirement. It was not designed for that purpose, and many students will fail who should have passed.
State Commissioner of Education Deborah Gist said Sgouros was wrong because he is not a psychometrician. She did not explain why he was wrong, not did she understand that psychometricians would likely agree with Sgouros.
