The purpose of this subchapter is to implement the Behavioral Health Partnership Program. This program delivers mental health and substance use resources to school districts served by a regional education service center and in which the local mental health authority (LMHA) or local behavioral health authority (LBHA) also delivers services. The program allows LMHAs and LBHAs to request a waiver to employ a professional who fulfills the duties outlined in Texas Education Code §8.152.
