Officials are calling on the state to close a legal loophole allowing sex offenders to live close to pre-K facilities.
Members of the Independent Democratic Conference say there are 93 sex offenders living within 1,000 feet of such sites.
They say it's currently legal because standalone pre-K sites are not covered under the legal definition of a school.
Lawmakers say current legislation needs to be expanded to protect some of the city's most vulnerable students.
"There's 1,800 UPK programs in the city of New York. They need the same protection as anyone else," said Jeff Klein, leader of the state Senate's Independent Democratic Conference. "Certainly, 4-year-olds deserve the same protection as any other child from dangerous sexual predators."
"And there's a lot of parents across the city that are very excited about sending their kids to school for the first time within the next two weeks. And we want to make sure that they know their kids are going to be safe," said state Senator Diane Savino of Staten Island.
IDC officials say there are also at least 60 sex offenders violating the current law, which prohibits level 2 and 3 sex offenders from living within 1,000 feet of schools.
