Kudos to Bronx and Brooklyn Borough Presidents Ruben Diaz Jr. and Eric Adams for pushing to expand the city schools’ Gifted and Talented programs.

They’re right: Boosting access to G&T is one right way to increase opportunity to enter the city’s elite high schools. We look forward to hearing their task force’s recommendations on enlarging G&T.

We have no real problem with the test that lets kids enter these programs in grades K-3. But too many districts have no G&T programs — which inevitably means plenty of parents never try to get their children in.

Families for Excellent Schools found that 63,000 city kids have no access to in-district G&T. Four entire districts in Brooklyn and The Bronx lack a single local G&T program — and travel out of district, to a citywide class, is a big deal for a toddler.

It’s just another case where a child’s ZIP code can limit his or her destiny.

Not that the problem stops there. A new StudentsFirstNY report uncovered New York’s “middle school deserts.” In eight of the city’s 32 school districts, not a single (non-charter) middle school achieved the citywide average proficiency in reading or math on the 2016 tests. And it’s hard to prepare for the elite-schools admission exam if your middle school is a joke.

Until the city starts delivering real opportunity at regular public schools in every ZIP code, the only hope for countless kids rests in charter schools — which continue to be oases in educational deserts.
