The purpose of this document is to provide the reader with a general understanding regarding the roles and responsibilities of professional student support personnel in West Virginia schools and how, through a collaborative partnership, they can work together to provide a safe and supportive learning environment for WV students. Research confirms that students do better in school when they receive social-emotional and mental health support. They miss fewer classes, concentrate more, are less likely to engage in risky or antisocial behavior, and achieve higher test scores. The most effective way to implement integrated services that support school safety and student learning is through a school-wide multitiered system of support (MTSS). Effective MTSS requires: (1) adequate access to school-employed professional student support personnel and community-based services; (2) integration of services (social-emotional learning, mental health, medical health, behavioral supports, academic supports, school-based services, and community services); (3) adequate staff time for planning and problem-solving; (4) effective collection, evaluation, interpretation, and use of data; (5) patience, commitment, collaborations, and strong leadership; and (6) understanding the various roles of the many student support personnel and how they work together for the benefit of every child. The West Virginia Department of Education (WVDE) recognizes the effectiveness of a multi-tiered system of support and is committed to ensuring equitable education opportunities through the West Virginia Tiered System of Support (WVTSS), a multi-tiered systems framework. WVTSS emphasizes the integration of academics, behavior, and mental health as uniformly critical to student success and focuses on the cohesive system of support rather than interventions alone.
