New York is requiring that each public and charter school post the phone number for the state's child-abuse hotline in a prominent location where students can see it.
The law, recently signed by Gov. Andrew Cuomo, directs the state education commissioner to issue-related regulations.
Legislative sponsors say one in four girls and one in six boys nationwide are molested, mainly at home, and the notices offer a simple and effective way to let victims report abuse.
The statewide toll-free number is 1-800-342-3720.
The Office of Children and Family Services says the hotline receives calls of alleged abuse or maltreatment around the clock every day.
