Multi-Tiered Intervention

The multi-tiered approach has three levels of intensity which are coordinated to student needs based upon research-based interventions.  The three levels of intervention include the universal, supplemental, and intensive tiers. The universal tier (Tier 1) is comprised of 80-90% of the student population.  Tier 1 includes high quality core instruction.  Tier 2 is the supplemental tier and includes 5-15% of the student population. This tier includes evidence-based interventions of moderate intensity.  Tier 3 of the model is the intensive tier that that is comprised of 1-5% of the student population.  The intensive tier’s prevention level includes individualized interventions of increased intensity for students who show minimal response to tier two preventions.
