The City Council voted to approve a bill on Dec. 19 to allow small, non-public schools to be reimbursed by New York City for the cost of hiring security guards — just as larger schools are. Specifically, the bill will expand the number of non-public schools eligible for the city’s reimbursement program. That program, established in 2015, allows schools with an enrollment of at least 300 students to qualify. The new bill lowers that threshold to 150 students.
