The city has shut down nine pre-K centers just two days before classes start, and delayed the start of 36 others.
The de Blasio administration says the shuttered programs were unlikely to open this year because of safety and integrity concerns.
The Department of Education says it's in contact with the parents of the more than 250 students from those programs who will need to be relocated.
The 36 centers with delayed opening are likely to be ready by next week, according to the city.
Almost 1,700 pre-K programs are set to start on Thursday—serving nearly 53,000 kids.
