With increased emphasis on diversity, equity, and inclusion in teacher preparation, there is a need for efficient instruments to support survey research of teachers' equity-oriented preparation. This article describes the development and initial validation of the Teacher Preparation for Equity Scale, a broad measure of teacher perceptions regarding the extent to which their preparation program emphasized elements of equity-oriented preparation. Public school, PreK-12, U.S. teachers (n = 757) from a Mid-Atlantic state responded to a survey about their equity-related beliefs and assessment practices. We constructed the scale to capture programs' emphasis on aspects of equity orientation and reflective practice, anticipating two separate and related factors. Evidence supports two factors, equity-oriented preparation (4 items) and reflective practice (3 items), with a defensible general factor (7 items) that we term the Teacher Preparation for Equity Scale. The measure can be used to examine in-service teachers' perceptions of their preparation experiences for equity-oriented teaching.
