As New York City emerges from the viral trauma of the last few months, one would imagine our Schools Chancellor Richard Carranaza would be hard at work figuring out how to revive the education system come September.

Instead, Carranza remains ­intent on making the good schools bad — and doing nothing to help the failing schools he pretends to care about.

Carranza’s miserable tenure has been marked by this monomaniacal obsession. He and his boss, Mayor Bill de Blasio, are singularly focused on schools removing “screens” such as grades, test scores, recommendations and ­attendance used to admit students to selective schools. The kind of schools, to be clear, that their own kids attended.

Officially, Carranza’s Department of Education laughably claims to take no position on whether schools use screens. But as Selim Algar reported in these pages recently, one of DOE’s allies in the destruction of good schools made an oopsie.

The activist Miriam Nunberg of the New York City Alliance for School Integration and Desegregation said the department is busy trying to mobilize opposition to screened-school backers.

“DOE folks have reached out to many of these partners, asking our people to make more noise,” she wrote. And she called on recipients to launch an e-mail campaign, along with other actions.

Then, noticing her mistake, Nunberg followed with an e-mail requesting that recipients “not forward the full text of the e-mail I sent, since it has come to my attention that it might be problematic for word to get out that the DOE is encouraging folks to make noise” against screening.

It’s obvious to anyone paying attention that Carranza has not been some disinterested observer of parental wants. In 2018, Carranza said: “I think the very fact that we’re talking about screening is an issue. Why are we screening kids in a public school system? That is, to me, antithetical to what I think we all want for our kids.”

Except, again, it wasn’t antithetical to what Carranza wanted for his own daughter, who attended just such a school.

And earlier this month, as tens of thousands of New Yorkers died around him, Carranza callously said: “Never waste a good crisis to transform a system. We see this as an opportunity to finally push and move and be very strategic in a very aggressive way what we know is the equity agenda for our kids.”

Parents shouldn’t let him “use” the coronavirus crisis to recreate our schools in his lefty image.

The problem that Carranza and de Blasio have with screened schools is that they act as a reverse mirror of the Department of Education’s failures. When a middle school accepts kids with good grades and high scores but only pulls those kids from a few elementary schools, the problem isn’t with the screens — but with the failing system.

Instead of working to fix those failed elementary schools, getting rid of middle- or high-school screens plasters over the problem without doing any of the internal work necessary to get them to succeed.

Removing the metrics by which good students are judged is important to the smoke-and-mirrors routine preferred by the chancellor and mayor. If there are no standards, then no student is failing, and no school is bad. Voilà!

The chancellor’s priority right now should be looking to September and how to reopen our schools. The economy can’t function without schools being in session, and instead of wasting his time on his leftist fantasies and trying to astroturf support for his backward ideas, Carranza needs to actually do the work he is being paid nearly $400,000 to do.

It’s far easier to destroy good schools than it is to fix bad ones. But reversing failure is what Gotham hired the chancellor to do. Parents should “make some noise” and remind him of that.
