This document discusses Response to Intervention (RTI) approaches for English learners. It notes that implementing RTI for culturally and linguistically diverse students requires understanding their backgrounds and needs. Tier 1 interventions involve classroom modifications and accommodations with documentation. Tier 2 adds further modifications and progress monitoring. Tier 3 provides intensive, small group instruction by highly trained teachers with weekly monitoring. Secondary English learners face challenges with academic literacy, but effective Tier 1 instruction incorporates socioculturally aware practices, rich texts, vocabulary instruction and differentiation. Organizing RTI with options like sheltered instruction observation protocol can help secondary English learners access grade-level content.
