Tiered Supports and Services

ennsylvania’s integrated tiered model is defined as having 3 tiers. All students, including students with disabilities, are provided meaningful access to high-quality, standards-aligned core instruction (Tier 1/universal and classwide intervention). Tier 2 support is more targeted and generally reserved for 10-15% of students. Tier 3 is considered the most intensive support and service for approximately 3-5% of students. It should be noted that advanced tier levels of support and services (i.e., Tiers 2 and 3) cannot replace or compensate for limited fidelity at Tier 1.  Each tier is delivered with fidelity and within the context of evidence-based practices matched to student needs and informed using a continuum of reliable and valid data sources.
