Late Friday, the United Federation of Teachers quietly announced the closing of the last UFT-run charter school — a tacit admission that charters’ success isn’t about any special privileges, but rather their freedom from micromanagement, including the burdens that teacher-union rules put on regular public schools.

Of course, the UFT pretends otherwise about the UFT Charter High School, as it did about the already-shuttered UFT middle- and elementary-school charters. But the reality is that the UFT HS had drastically declining enrollment (down from its 400 peak to just over 200) — the ultimate sign that parents weren’t buying it.

It also attracted far fewer English language learners and special-education students than the charter sector as a whole — a clear sign it couldn’t deliver for the kids that need the most help.

The union opened these schools over a decade ago to prove its approach to education worked. Whatever excuses it offers now, the reality is that it proved the exact opposite.
