Comprehensive school-based mental health supports form the foundation that allows for equitable academic pathways for all youth. True success in supporting the well-being of students’ mental, behavioral and emotional health requires a systems-based approach. Washington is engaged in generational work focused on comprehensive school-based mental health systems utilizing a MTSS approach. These efforts are far-reaching, span multiple decades, and have positively impacted the lives of thousands of students and their families. Washington will give a brief overview of the history, the lessons learned and the models for success that others can utilize to grow and build their own school-based systems of mental and behavioral health to meet the needs of all students equitably. Participants will learn recommendations towards building and growing equitable school-based mental health systems that prioritize community connections, youth voice, adult wellness, and sustainable pathways forward.
