The school board of any school district may authorize and commission school officers to enforce laws relating to crimes committed on school premises, at school activities, and on school buses operating within the school district only upon the execution of a memorandum of understanding with each municipal law enforcement agency and county sheriff’s office which has law enforcement jurisdiction over the school district’s premises and location of school activities, provided that the memorandum shall not grant statewide arrest authority. School officers shall be licensed peace officers, as defined in section 590.010, and shall comply with the provisions of chapter 590. The powers and duties of a peace officer shall continue throughout the employee’s tenure as a school officer.

School officers shall abide by district school board policies, all terms and conditions defined within the executed memorandum of understanding with each municipal law enforcement agency and county sheriff’s office which has law enforcement jurisdiction over the school district’s premises and location of school activities, and shall consult with and coordinate activities through the school superintendent or the superintendent’s designee. School officers’ authority shall be limited to crimes committed on school premises, at school activities, and on school buses operating within the jurisdiction of the executed memorandum of understanding. All crimes involving any sexual offense or any felony involving the threat or use of force shall remain under the authority of the local jurisdiction where the crime occurred. School officers may conduct any justified stop on school property and enforce any local violation that occurs on school grounds. School officers shall have the authority to stop, detain, and arrest for crimes committed on school property, at school activities, and on school buses.
