Tier III / Intensive Instruction
Tier 3 refers to evidence-based intensive targeted interventions for students who have not responded adequately to Tier 1 or Tier 2 supplemental, targeted instruction. This small percentage of students usually have severe and multiple skill difficulties and require instruction that is more explicit, more intensive, and specifically designed to meet individual needs. Diagnostic and weekly or bi-weekly progress monitoring assessments are utilized extensively with this group of students to inform instruction and to provide appropriate, targeted intervention, materials, and strategies. Tier 3 instruction takes place in addition to Tier 1. If progress monitoring and diagnostic assessments indicate that a student is not making adequate progress, a student may need a replacement of the core program (Tier 1 instruction)or be referred for further evaluation.
