As a professional development tool, coaching is a process of systematic observation of another's instructional behavior with subsequent nonjudgemental feedback. It is a natural follow-up to a recent training event or experience and is extensively used within industrial contexts. Well-trained feedback personnel, including peers, team leaders, master teachers, career ladder representatives, building principals, and school district supervisors, are essential to coaching success. Several coaching programs at the college and school district level are described to illustrate the various ways that staff development coaching can be conducted. (CB)
