Gov. Kathy Hochul’s plan to allow about 100 more charter schools to eventually open in the city should be a no-brainer, for all the reasons The Post has laid out in our “Free the Charters” series this last week:

If the cap continues to deny them that possibility, they may well leave the public schools (and even the city) entirely: DOE enrollment is already falling drastically, with no end in sight.

“I have to say, I really feel that [first] charter school saved my life and my daughter’s life,” says Marcia Ward-Mitchell, whose daughter Kimana, who has autism and ADHD, is now 14 and thriving at her third city charter school.

“She can read,” says Azalia Lopez Volpe, “she can read. Like, she can read!” of her daughter Violetta, diagnosed with dyslexia in first grade and only getting the help she needed after switching to Bridge Preparatory Charter School on Staten Island, the city’s first public school that caters specifically to students with literacy disorders.

Sure would be nice to have such schools in all five boroughs — but the state’s current “charter cap” for the city prevents it.

Hochul’s plan simply does two things: 1) Permits about a dozen charter allowances “used up” by schools that closed to be re-used by new ones. 2) Removes the NYC-only cap on total charters allowed so that the 100 or so still available in the rest of the state can be issued in the five boroughs.

Of course, after two decades when the Empire State’s “experiment” with allowing charters has proved a huge success, any policy reason for capping them at all vanished long ago.

Yet the Legislature resists, thanks solely to the power of the teachers unions — the city United Federation of Teachers and New York State United Teachers — which hate charters because they’re mainly non-union.

The UFT and NYSUT are elephants in Albany, spending millions in members’ dues to buy support and mounting hefty get-out-the-vote operations that are key to many legislators’ re-elections. Somehow, lawmakers normally obsessed with race ignore the fact that the overwhelmingly white unions fight furiously to prevent new hope for mainly minority families that want better futures for their children.

We pray that the governor stands strong, not using the charter issue as a bargaining chip to be traded for some other part of her agenda. And that enough lawmakers listen to their consciences, not to this special interest, and stand with the children.

The right choice couldn’t possibly be more clear.
