MANHATTAN - Registration is now open for pre-K in New York City.

Children who turn 4 years old this year are eligible to be enrolled in either half-day or full-day pre-K in New York City. Parents can either register online or in person

Parents have until April 23 to register their children in one of the 570 public schools citywide that have pre-K classes. In the summer, parents will find out where their children will attend pre-K, based on where they live and what school they're able to get into.

About 20,000 pre-K seats are available right now, as Mayor Bill de Blasio's universal pre-K is on hold, pending on how the budget works out in April. If the funding goes through, the number of available seats could jump to more than 50,000.
