The California behavioral health ecosystem includes the California Legislature, the overarching state law called the Mental Health Services Act (MHSA), and various California agencies, oversight bodies and training providers.
This illustration maps out the various top-level MHSA-focused entities:
California Legislature

Mental Health Services Act (MHSA)
2004 Proposition 63 is a one percent tax on residents with incomes above $1 million. This tax currently funds approximately 24% of California’s mental health services budget statewide and a varying percentage of each county’s annual budget.
The MHSA also speaks to various facets of planning, procuring, and administering mental health services through a variety of stakeholders from state and county Health & Human Services departments, Behavioral Health Advisory Boards, including ensuring active citizen-consumer engagement.
Mental Health Services Oversight & Accountability Commission (MHSOAC)
MHSOAC’s role is to oversee the implementation of the Mental Health Services Act (MHSA). The MHSOAC is also responsible for developing strategies to overcome stigma. At any time, the MHSOAC may advise the Governor or the Legislature on mental health policy.
MHSOAC’s mission is to provide vision and leadership, in collaboration with clients, their family members, and underserved communities, to ensure Californians understand mental health is essential to overall health. Hold public mental health systems accountable. Provide oversight for eliminating disparities; promote wellness, recovery and resiliency; and ensure positive outcomes for individuals living with serious mental illness and their families.
