Multi-Tiered System of Supports (MTSS)

The MTSS journey in Pomona Unified is underway! We are eagerly working together to create a Multi-Tiered System of Supports with a foundation of equity and excellence for every student, in every classroom, every day! The MTSS Task Force met monthly to explore our current systems, processes, and strategies to systematize and refine our practices. Our MTSS journey continues as district leadership continues to refine processes and identify practices that impact student achievement.


Multi-Tiered Systems of Support (MTSS) is an integrated, systemic framework guided by data, grounded in evidence-based culturally responsive practices, and committed to teaching the whole child. MTSS ensures that ALL students receive equitable academic, behavioral, and social-emotional supports that are timely and responsive in order to achieve college and career readiness.


In California, MTSS core components work together to create an integrated, comprehensive framework that focus on the California State Standards, core instruction, differentiated learning, student-centered learning, individualized student needs, and the alignment of systems necessary for academic, behavior, and social success. MTSS offers the potential to create needed systematic change through intentional design and redesign of services and supports that quickly identify and match the needs of all students in general and special education contexts.
