Metro Nashville is abandoning “one-and-done” professional development in favor of coaching models designed to make training stick—especially for teachers supporting English learners. Jenna Davis, an English-learner coach, is present throughout the year to provide continuous feedback, facilitate professional learning communities, and translate PD into classroom practice rather than deliver a single workshop. The district’s approach ties coaching to a co-teaching model in which English-learner specialists work in the same classroom with general education teachers. The partnership is meant to reflect shared responsibility for educating English learners, who account for 60% of Mt. View Elementary’s student population in a district of 81,000. The change highlights a broader implementation issue: training alone is insufficient if teachers do not receive feedback loops, time to collaborate on real classroom problems, and on-the-ground reinforcement. Nashville’s in-house coaching structure is presented as a response to those gaps.
