📐

Deep Standards Alignment

Framework Mapping

Danielson, Marzano, Understanding by Design, and state-specific frameworks. Your lesson speaks your evaluator's language.

Student-Level Differentiation

Readiness, interest, learning profiles, IEPs, ELLs, MTSS tiers. Tangram knows your students — not just your subject.

Observation-Ready Output
