The main purpose of this legislation, known as the "Expand the Behavioral Health Workforce Now Act," is to enhance the education, training, recruitment, and retention of mental health and substance use disorder care providers. It aims to improve access to mental health services, particularly in rural and underserved areas, by ensuring that there are enough qualified professionals available to meet the needs of individuals requiring care. Key provisions of the law require the Secretary of Health and Human Services to provide guidance to states within a year of the law being enacted.
