The Chicago Police Department would receive $13 million annually in compensation for the 152 full-time police officers currently assigned to the Chicago Public School District’s 106 high schools, under an agreement introduced by Mayor Rahm Emanuel.

According to the Chicago Sun-Times, this marks an increase from the $8 million CPS had been paying up to 2011, and a reduction from the amount that Emanuel imposed when he took office. At that point, he refused a previously negotiated 4-percent raise for teachers in order to retroactively pay the Chicago Police Department for their school security services. The $8 million per year schools had been paying was actually costing the CPD around $25 million per year.

Police department spokesman Adam Collins said the new intergovernmental agreement “covers the costs of a range of CPD services and is not specific to only the number of officers assigned to” high schools. “It also encompasses other efforts to ensure safety, such as roving sergeants and other response needs,” Collins told the Sun-Times.

The new agreement again calls for uniformed officers to be stationed in high school rooms outfitted with “computer terminals connected to the CPD network for the purpose of processing juvenile offenders apprehended,” the article reports, as well as to maintain daily reports on crimes and arrests at high schools.
