An Assembly spokesman on Tuesday morning confirmed the chamber would return on Wednesday in a special session to consider a measure that would extend mayoral control of New York City schools.

The session is being called by Gov. Andrew Cuomo after an agreement with lawmakers to extend the program was not reached last week, the final scheduled week of the 2017 legislative session.

The session will likely include a pension sweetener measure for New York City police and firefighters — a measure that had been favored by Senate Republicans.

GOP lawmakers in the Senate had also sought to strengthen charter schools as a condition for extending mayoral control — a non-starter with Speaker Carl Heastie, a Bronx Democrat.

The Assembly in May approved a version of mayoral control that packaged county and local government tax provisions.

The legislation to be considered Wednesday is not expected to expand charter schools.

Governors can require lawmakers return to Albany to take up session, but cannot force action in the chambers themselves.

As such, Cuomo has sought to exercise that power cautiously. At the same time, special sessions have been rare in Albany under Cuomo.

A deal for lawmakers to return late last year that would have likely led to a pay raise for the Legislature fell apart.

The package of legislation is expected to be narrowly prescribed in order to avoid a free-for-all of measures that were not accomplished, but had been heavily lobbied for in the last several weeks.
