Collaborative Learning Community: Response to Intervention (RTI) Model Brochur

In your assigned CLC groups, you will develop a three-tiered RTI model brochure for parents as a resource regarding students struggling with reading that includes the following:

     1.    Tier 1: Screening and group interventions
     2.    Tier 2: Targeted interventions
     3.    Tier 3: Intensive interventions and evaluation

My questions are   

1. What makes RTI effective?
2. How should the three intervention tiers of RTI model be utilized? Include an RTI intervention tier flowchart.

I need them for the three sessions
