Instructional coaching has emerged as a prevalent and much-lauded instrument for capacity building. This essay argues that coaching can be aligned with teacher evaluation systems to work toward the effective implementation of instructional reforms, including Common Core State Standards and Next Generation Science Standards. Within the current policy context, coaching can support reform by (a) developing shared understandings, (b) modeling practices, and (c) brokering ideas. We discuss examples of coaches' leadership actions related to the evaluation process, thus illustrating the potential for coaching to promote coherence in instructional improvement. We conclude by discussing barriers to the enactment of reform-aligned coaching as well as implications for leaders positioned at multiple levels of the education system.
