This practical resource is grounded in a simple but powerful premise: that school-based coaching programs can be designed in a way that more directly impacts student achievement. In a student-centered coaching relationship, the focus is on using data and student work to drive conversations between coaches and teachers to make informed decisions about instruction. In other words, coaches and teachers work collaboratively to support students. The book also underscores the critical role of the principal in developing systems and structures to support teacher learning and fostering a culture of learning. The book is suitable for use with both new and experienced coaches and the principals who support them.
