Three schools share the Wadleigh Secondary School building in Harlem. Two have declining enrollment — the usual result when families in a neighborhood realize a school just isn’t that good. By contrast, families love the third school, Success Academy Harlem West, where kids post great test scores. The city is taking three classrooms from the shrinking schools — and giving the space to a fourth institution rather than to SA Harlem West. Success notes that the DOE plan will force it to squeeze 14 more kids into each of its classrooms than the average for one of the two other schools. Team de Blasio is stonewalling Success space requests not just in Harlem, but all across the city.
