Instruction for multiple tiers in a whole group setting
Tier 1: Targeted Support
This is the most basic form of support your school provides. It refers to general academic and behavior instruction designed and differentiated for all those in the building. Here, data is useful in providing feedback about what is working at the level of curriculum, instruction, and assessment.
Tier 2: Universal Support
This is a more focused form of support, wherein one receives supplementary help that aids to align work with established goals. A student struggling in math, for instance, might receive targeted help on concepts he is not understanding, perhaps with others. Here, data becomes important to isolate where the struggle is occurring exactly.
Tier 3: Intensive Support
Support usually involves individualized attention and extended time helping to align a teacher, for instance, with the teaching goals she is struggling to meet. Data is useful in this context in order to provide evidence of how a teacher has progressed and what areas continue to be a challenge.
