The term Professional Learning Community (PLC) has become commonplace in the field of education. Educators use this term to describe multiple combinations of individuals with an interest in education. Grade-level team meetings, groups meeting to read a common book, weekly data meetings, even a high school department meeting have been called PLCs. While these groups all have a place, they are not what is meant by a PLC. More accurately described, PLCs are a group of educators in collaborative teams that are committed to increasing student achievement. There are three big ideas that represent the core principals of a PLC: focus on learning rather than teaching, work collaboratively, and hold yourself accountable for results.
