In the fall of 2007--aware that the continuing professional development of teachers is paramount to quality education--John Baird, head of Westtown School (Pennsylvania), asked the faculty Professional Development Committee (PDC), consisting of faculty representatives from all three divisions of the school, to design a "professional growth cycle" as a framework for all continuing faculty growth and development efforts. The author's faculty PDC had already been working for several years to create a growth-oriented faculty culture through a variety of initiatives. These programs served as a positive backdrop for taking the next step in furthering their growth as a professional community of learners. The author believes that building an authentic community of learners means encouraging colleagues of all age and experience levels to engage in an ongoing dialogue about teaching and learning and to support one another's professional growth. Doing so offers each the opportunity, "to work toward one's growing edge" in an atmosphere of collaborative learning.
