Fall enrollment for NYC's free Pre-K program to begin Monday

NEW YORK (WABC) -- On Monday, fall enrollment begins for New York City's free Pre-K program.

Sunday, Mayor Bill de Blasio joined volunteers at Yankee Stadium to spread the word about how to sign up for classes.

Universal Pre-K launched last year with nearly 53,000 young students. Now, the mayor and supporters say they are working to increase that number to include all eligible 4-year-olds in the five boroughs.

Meanwhile, some civil liberties groups objected to the city's proposal to allow prayer breaks at public Pre-K programs run by religious organizations.
