States in the midst of implementing evaluation reforms face a common dilemma: how to ensure that all your districts are implementing quality educator evaluation systems while still providing them with the flexibility to design systems best suited to their own unique needs. One answer is to create an equivalency process (also known as an approval process) to verify that districts meet state requirements for evaluation components and processes. An equivalency process allows a state to provide quality assurance for district evaluation plans. States review documentation and evidence submitted by a district about its evaluation system. In designing an equivalency process, states typically include clear guidance on the requirements of the evaluation system, recommendations on best practices, rubrics or processes for meeting the requirements, and examples of approved models or components. The nuts and bolts for creating an equivalency process, however, can seem daunting to sort out. In response to questions from the field, the Center on Great Teachers and Leaders developed a set of promising practices and recommendations for consideration when developing an equivalency process in one's own state.
