Peter Greene watched “All in with Chris Hayes,” in which Merryl Tisch and I discussed and disagreed about the value of the Common Core tests. The reason for the debate was the reports of large numbers of parents opting out their children.

Tisch, whom I have known for many years, is Chancellor of the Néw York State Regents. She defended the testing as necessary and helpful.

Peter Greene analyzed her changing rationales about why the tests are valuable.

She believes they help the neediest children, but of course these are precisely the children likeliest to fail. I don’t see how children gain motivation by failing a test that has been designed to fail 70% of all students.

She thinks that the opt outs are a “labor dispute” between the Governor and the teachers’ union. Unfortunately I did not have a chance to respond that parents do not act at the union’s command. They act in the best interests of their child.

Merryl Tisch is an intelligent woman, and I look forward to having a conversation with her, off-camera.
