Identification is now required before entering all school buildings in the North Babylon district.
Superintendent Patricia Godek enacted a stricter security policy on Monday Dec. 17, in which all visitors to the school buildings would first be greeted by security personel and asked for identification.
Security officials were on duty outside of each school Monday ready to check identification and be on the look out for any potential threats.
At the high school, students were asked for their identification before entering the school building, as well.
The policy will remain in effect until further notice, district officials said.
