Gov. Cuomo took a victory lap Wednesday following the bloodiest budget battle of his five-year tenure, claiming the Legislature’s approval of new teacher-accountability measures will be one of his “greatest legacies.”

The governor also hailed changes to the ethics law — requiring legislators who practice law to provide greater disclosure about their clients and outside income — as “transformative.”

“We want to know who is paying you. It is dramatic turn,” Cuomo said on an Albany radio show.

On both issues, an ebullient Cuomo dismissed critics of the hard-fought changes and even took a veiled shot at state Attorney General Eric Schneiderman, a fellow Democrat who on Monday slammed the governor’s ethics reforms as merely “tinkering around the edges.”

Schneiderman had proposed more sweeping reforms.

Cuomo pointed out that from 2008 to 2010 — when Schneiderman was a state senator — Democrats who controlled both houses of the Legislature failed to deliver tougher ethics rules.

“Why didn’t they do it when they controlled the entire state government,?” Cuomo asked on WCNY’s “Capitol Pressroom.”

Schneiderman declined to comment, but during a recent speech, conceded he was wrong back then for extolling “incremental” changes.

As for education, Cuomo’s new teacher-accountability system weakens the role of school districts and teachers unions in devising evaluation plans. The law also makes it easier to fire incompetent teachers.

In addition, teachers would be graded in part by outside observers and students’ performance on state tests would count more heavily in their evaluations.

“This is going to be one of the greatest legacies for me and this state when all is said and done,” said Cuomo, who withstood weeks of protests fueled by teachers’ unions and other anti-testing critics.

Several Assembly Democrats denounced the changes before grudgingly voting for them.

After complaining about “attacks on teachers,” Bronx Assemblyman Jeffrey Dinowitz literally held his nose with one hand as he voted “aye.”
