The Michigan Health Endowment Fund engaged Public Sector Consultants (PSC), a public policy research and consulting firm in Lansing, Michigan, to evaluate implementation of tiered positive behavioral interventions and supports (PBIS) and mental health services in two Muskegon school districts: Oakridge Public Schools and Holton Public Schools. The districts are implementing PBIS and mental health services using the Interconnected Systems Framework (ISF), which provides a structured approach for establishing these supports and services in schools. This effort is the school-based component of MYalliance, Muskegon County’s system of care comprising parents, schools, and agencies working together to improve services in Muskegon County to achieve better mental health outcomes for youth and young adults.
