Little attention has been given to better understanding how to effectively evaluate the work of instructional coaches. This study by Evthokia Stephanie Saclarides and Sarah Theule Lubienski illustrates how a new evaluation system for coaches was implemented in one mid-size, urban district. They describe two ways in which the Evaluation Tool detracted from the coaches' work to foster teacher improvement. Furthermore, they provide suggestions for school districts to consider when evaluating their coaches.
