Existing law requires the Commission on Peace Officer Standards and Training to establish and keep updated a classroom-based continuing training course that includes instructor-led active learning, such as scenario-based training, relating to behavioral health and law enforcement interaction with persons with mental illness, intellectual disability, and substance use disorders. Existing law requires the commission to make available the course to each law enforcement officer with a rank of supervisor or below and who is assigned to patrol duties or to supervise officers who are assigned to patrol duties. This bill would authorize the commission to partner with local departments of behavioral health, community-based organizations, or nonprofit organizations to establish and keep updated this classroom-based continuing training course. The bill would require a law enforcement officer with a rank of supervisor or below and who is assigned to patrol duties or to supervise officers who are assigned to patrol duties to complete the course. By imposing additional training costs on local law enforcement agencies, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
