Lawmakers took the first steps to formally rebuff the education changes approved in the state budget last month as the Assembly on Wednesday approved a package of measures aimed at slowing the implementation of the new teacher evaluation system.

The bill, approved by the Democratic-led chamber, passed overwhelmingly: 135-1.

The bill would extend the deadline for the Board of Regents to develop regulations for the new evaluation system and gives local school districts more time to implement the new performance review standards.

The measure also would reverse the linking of a boost of state education aid to the enactment of the new evaluations. More funding would be allocated to the Department of Education, about $8.4 million, to help districts enact more locally based testing.

Republicans in the Senate are considering a similar measure that will also address the controversial Common Core education standards and extend the time for the development the evaluation criteria.

The Board of Regents currently has until June 30 to determine how much weight to give classroom observation and at least one standardized test on a teacher’s evaluation. A second test can be added based on collective bargaining at the local level.

Still, it remains to be seen whether Gov. Andrew Cuomo will embrace these changes. The governor pushed hard to include the new evaluation system in the budget, which was included in an omnibus spending bill for school as well as the implementation of new ethics legislation.

The measures approved today by the Assembly was one supported by the New York State United Teachers union, which has tangled with the governor on education reform policies.

“We commend the Assembly and its leadership for taking a strong step toward getting our schools back to what’s really important: teaching and learning,” New York State United Teachers union President Karen Magee said in a statement released on Tuesday and before the bill’s passage. “This bill, while not perfect, clearly begins meeting the concerns of students, parents and educators.”

Cuomo’s allies in the education reform movement, meanwhile, blasted the move.

“It’s disheartening to learn that certain lawmakers who approved teacher assessment reforms during the budget process have flip-flopped after a special interest group complained about the agreement,” StudentsFirstNY Executive Director Jenny Sedlis said in a statement. ”If New York State is serious about improving education, it must move forward with a better teacher evaluation system.”

Cuomo is pushing ahead in the post-budget legislative session this month with measures that would lift the statewide cap on charter schools as well as create an education investment tax credit.

Both proposals are opposed by NYSUT.
