Mental Health First Aid Training; require for certain public school personnel and school resource officers.

HB 591 requires all Mississippi public school teachers, staff, and school resource officers to complete science-backed mental health first aid training approved by the state Department of Mental Health before the 2025-2026 school year. School boards must create policies for how often this training is repeated and issue certificates of completion that satisfy future district requirements. The bill directly affects over 100,000 school personnel statewide by mandating this training as part of their professional development. It does not alter existing school discipline policies but adds a new requirement for staff to recognize and respond to mental health crises.
