The city and teachers union have resolved their main disagreement over a teacher evaluation system just as Gov. Cuomo is expected to announce a deal at the state level.

The sticking point has been the union’s insistence that teachers be allowed to appeal poor ratings to an independent arbitrator, something that’s not currently allowed.

While that matter has been resolved, the two sides still have to hammer out some final details before the overall deal can be considered done, according to a source.

A city hall source said an overall deal has been reached, but the teachers’ union would not confirm it.

A final resolution would clear the way for the state to reinstate $60 million in federal funding that was suspended when the city and UFT couldn’t reach an agreement by a Dec. 31 deadline.
