ACEs Aware Data Reports

The mission of ACEs Aware is to promote universal screening for Adverse Childhood Experiences (ACEs) across the Medi-Cal population and train health care teams to prevent, identify, screen, and respond to childhood adversity and toxic stress.

We are dedicated to measuring and communicating data that tracks progress toward achieving our goals.
