Alexandra Robinson clearly deserves firing, but it shouldn’t stop there. Department of Education higher-ups also need to answer for the bungled drive to get GPS working on every city school bus.

As The Post reported Monday, the DOE spent nearly $9 million to get trackers on the entire 6,000-bus fleet — starting in 2015. Four years later, the system’s still not working.

Chancellor Richard Carranza fired Eric Goldstein, the head of pupil transportation, after the missing-bus disasters as school opened in 2018. But now another probe blames Robinson, who heads the DOE’s office of pupil transportation, calling for “discipline up to and including termination” for her “consistent, willful neglect of the [GPS] project’s problems,” “mismanagement” and “failure to take corrective action even when advised of significant issues.”

Things like the system showing school buses off the coast of Africa and the fact that it depended on drivers turning the GPS on — and most never did.

The DOE vows to get GPS right next year. Its clear backup plan: Find another scapegoat.
