Gov. Cuomo blamed both sides today for the failed teacher evaluation talks, calling it “a tragedy” that city schools are about to lose at least $250 million.

“Almost every school district got it done in the state except New York City. There’s a very small handful that didn’t get it done and New York City is by far the largest. They asked me several times would I extend the deadline and I saw no, because a deadline is a deadline,” Cuomo said on WOR radio.

“You extend a deadline and the next time you say it’s a deadline it’s really not. So they missed the deadline and the city’s not going to get the funding and it’s a tragedy. It really is a tragedy.

“And they both failed. One is going to point at the other and they’re asking me who’s right and who’s wrong. I don’t know who’s right, who’s wrong. But I know they both failed because we needed an agreement and now the education system in the city is going to suffer.”
