The Professional Learning Community model of professional growth an development is an increasingly popular method of teacher training. Commonly abbreviated and referred to as PLCs, this style of professional learning is characterized by its focus on small groups and individualized learning. While the PLC has nearly become a standard feature of the American public school, many teachers and administrators have reported difficulty in implementing a meaningful process. By their very nature, PLCs are unique to each school environment, but the research described in this paper suggests that effective PLC processes share a set of common characteristics. This report makes seven best practice recommendations for implementing the professional learning community model. [This report was published by the Bluegrass Center for Teacher Quality, Inc.]
