This resource was prepared in response to a request for information about what States with Race to the Top -- Early Learning Challenge (RTT-ELC) grants are doing to support coaching as a professional development strategy. This information will be helpful to other States as they explore ways to support early childhood educators in improving their knowledge, skills, and abilities. To address this request, ELC TA reviewed the most recent RTT-ELC data available. In the spring of 2016, the 20 RTT-ELC States submitted 2015 "RTT-ELC Annual Performance Reports" (APR) to the Department of Education and the Department of Health and Human Services detailing their grant work in 2015. In their RTT-ELC applications, all States were required to focus at least some portion of their State plans and budgets on workforce-related projects. States addressed one or both components of Focused Investment Area D, to support their early childhood education workforce. This report provides examples of a representative sample of the innovative workforce activities related to coaching that States described in their 2015 APRs. These examples include coordinating coaching at the State level; collaborating on development/implementation of competencies, credentials, and models for coaching; providing professional development for coaches; and evaluating the coaching model.
