Tier 2 is where MTSS either works or collapses. The difference between a small group that moves kids and a small group that just keeps them busy isn't mysterious — it's structure, data, and fidelity. The Tier 2 Small-Group Kit gives you all three in one place. Built for interventionists, classroom teachers pulling their own groups, instructional coaches, RTI/MTSS leads, and building administrators. Works whether you inherited a Tier 2 system that's drifting or you're building one from the ground
