Step 5: Three-Tiered Instructional/Intervention Model
(Match Supplemental and Intensive Interventions with the Learning Deficit.)
The Three-Tiered Instructional/Intervention Model begins with a deep dive into Tier 1 Instruction. The resources provided cover literacy and mathematical best practices. You will also find the ECATS MTSS Early Warning System that should guide conversations and problem-solving while provide Tier 1 instruction, supplemental supports, and intensive supports.
In addition to academic supports, social-emotional and behavioral growth are layered on to core curriculum and instruction, with increasingly intensive supports based on students’ needs.
Core | All Students 80-85%: Core is the first level of prevention and focuses on instruction, providing a strong foundation.
Intervention | Targeted Group of Students 10-15%: Intervention may benefit students who are not making adequate gains from Core alone. Intervention addresses struggling students by matching high-quality intervention to their individual needs.
Intensive Intervention | Targeted Group of Students 5%
More intensive interventions may be needed for smaller groups or individual students. The intervention must match the area of need.

Program materials are made available by Duplin County Schools to match the needs of our core, supplemental, and intensive learners. Programs are tools for teachers, to use along with strategies, to ensure that coordinated and comprehensive teaching and learning are provided.
Begin at Tier 1 to teach and assess students to determine the next steps for
Tier 1 differentiation and/or Tier 2 or 3 intervention matching.
