HB 1173 allows licensed psychologists in Oklahoma to prescribe medication for mental health conditions under two certification pathways. Psychologists seeking a "conditional" certificate must complete advanced training (including 450+ hours of coursework and supervised practice) and work under a supervising physician. Those qualifying for a full "prescription certificate" meet additional requirements, including 400+ hours treating 100+ patients, enabling independent prescribing without physician supervision. The bill directly affects psychologists seeking prescribing authority, setting specific educational and clinical standards for both certification levels, effective November 2025.
