This document argues that mental health education should be mandatory curriculum in U.S. schools. It notes that mental illness is the leading cause of disability among those aged 15-44 and is disproportionately impacting marginalized communities. The document advocates for mental health education to reduce stigma, allow early detection and prevention, and help address societal issues like incarceration and economic deprivation that stem from unmet mental health needs. Implementing mental health education in high schools in a way similar to physical education could help prevent dropout rates and create a healthier society with lower prevalence of mental illness.
