Definition: A multi-tier approach is used to efficiently differentiate instruction for all students. The model incorporates increasing intensities of instruction and assessments offering specific, research-based interventions matched to student needs driven by data.
TIER 1
Focus – All Students
Instruction and Supports – district curriculum and instructional practices that are evidence-based; aligned with state or district standards; incorporate differentiated instruction
Setting – General classroom (small and large group)
Assessment – Screening, continuous progress monitoring, and outcome measures
TIER 2
Focus – Students identified through screening as at risk of performing below expected outcomes
Instruction and Supports – Targeted, supplemental instruction practices that are evidence-based (large or small group); additional layer to Tier 1 Setting – General education and/or optimal setting for the need of students
Assessment – Diagnostic, Progress monitoring
TIER 3
Focus – Students who present with very low academic, high academic achievement, or behavior achievement, or who have not responded to Tier 1 and Tier 2 instruction, or students with disabilities who do not meet their IEP goals; additional layer to Tier 1 and Tier 2
Instruction – Intensive intervention adapted to address individual student needs through the systematic use of assessment data, validated interventions, and research-based instruction or behavior support strategies
Setting – General or special education depending on the needs of the student
Assessment – Diagnostic and progress monitoring
