The increasing diversity of students in Massachusetts makes growing a diverse educator workforce a critical policy goal for the Commonwealth. In recent years, state and local leaders have responded to this challenge with a variety of programs and policy changes. This report details these efforts and their considerable impact to date. However, the findings show the racial and ethnic differences between the state’s students and teachers will continue to widen through the end of this decade, if Massachusetts remains on the current trajectory. Employing a projection model developed by researchers at the Wheelock Educational Policy Center, the analysis models several hypothetical scenarios to close the gap. The report concludes with policy recommendations to accelerate the pace of change.
