It shall be the policy of the St. Tammany Parish School System that a cooperative effort be maintained between the school administration and law enforcement agencies. Law enforcement officials may be summoned to conduct an investigation of alleged criminal conduct on the school premises or during a school-sponsored activity or to maintain the educational environment. They may also be summoned to maintain or restore order when the presence of such officers is necessary to prevent injury to persons or property. Administrators have the responsibility and the authority to determine when the assistance of law enforcement officers is necessary. The School District’s administrators shall at all times act in a manner that protects and guarantees the rights of individual students and parents while also protecting the educational environment for all students and parents.
