It’s time for New York City Schools Chancellor Richard Carranza to go. Actually, it was time for him to go last year, when he was caught hiring a friend with a financial stake in a company that did business with the Department of Education. Or even earlier, when he declared war against Asian-American parents who ­objected to his anti-Asian school-integration schemes.

But now that Carranza has ­directly insulted parents, he ­really needs to go. He should ­resign — or Mayor de Blasio should fire him.

The last straw should have been Carranza storming out of a meeting with parents concerned about violence at their local middle school.

A shocking video taken at a once-highly regarded middle school in Bayside, Queens, MS 158, showed a 14-year-old girl beating on a younger girl while teachers made limited attempts to stop the brutality. As The Post has ­reported, this wasn’t the first major incident at the middle school in the last year; it came in addition to two instances of alleged sexual assault.

During the town-hall meeting with upset parents, Carranza ­refused to answer their questions, instead taking prescreened ones, until the anger in the room reached a boiling point, and the parents began to openly jeer. Then the chancellor walked out of the room and turned his back on their concerns. He later blasted the mother of the ­assaulted child for “grandstanding.”

I’m not the first to call for his firing, but I hope I’m the last. In June, nine City Council members wrote a letter to de Blasio calling for his ouster.

The tone-deaf mayor’s office shot back, insinuating that the signatories were — what else? — racist for calling for Carranza’s removal.

It added: “It’s a sad day for New York City kids when lawmakers care more about seeing their names in the press than about our school system.”

I’m not a lawmaker or a politician. I’m a writer and a mom with children in the city public schools. I care about kids, my own and others in the system. I feel a sense of solidarity with my fellow parents — and New York taxpayers.

And I’m fuming at Carranza’s callousness. He has been a disaster for the city in a number of ways, but snubbing parents concerned about their kids’ lives and safety is a historic nadir. To denigrate a mother grieving over her child being brutalized is intolerable.

In 2018, Carranza told The ­Atlantic magazine that when he became superintendent of San Francisco schools, he asked himself, “Do I try to be the stereotypical superintendent: political, hard to get a hold of, all of the things that you hear about superintendents? Or do I just be myself?” Touching.

Now it turns out that he is ­exactly that “political, hard-to-get-a-hold-of” school leader he pretended to denounce.

Even setting aside Carranza’s divisive race-baiting, pitting parents against each other and blasé attitude toward violence inside his schools, he should still be fired for sheer ­ineffectiveness.

“We stand with Chancellor Carranza and thank him for all he’s doing to bring equity and excellence to all our kids,” the mayor’s press secretary said in response to the June letter from lawmakers. But Carranza has plainly produced neither equity nor excellence in our schools.

His cockamamie plans — to get rid of screens at our best schools or bus children between distant neighborhoods to create the perfect hand-picked racial balance — have been met with widespread disapproval from parents of all races.

Focusing all fire on the best schools will do absolutely nothing to help the worst schools.

Yet he persists.

In San Francisco, Carranza left behind a desert. The otherwise glowing Atlantic profiler had to admit: “According to a report by Innovate Public Schools, a Bay Area nonprofit, in 2016, at the end of Carranza’s tenure, only 19 percent of African-American students were on grade level in reading, and 13 percent in math.”

That’s abject failure, and Carranza has to be stopped from replicating the same here. In ­another era, progressives would have raged against such minority achievement rates as a blight on America’s fundamental promise of equal opportunity.

I’m sure he will respond to this column with the old, false racism charges. Let him. This isn’t a ­serious man. And he isn’t who we need to run our schools. Carranza must go.
