What makes a powerful and results-driven Professional Learning Community (PLC)? The answer is PLC plus-- "plus" being the vital role teachers play in teaching and learning. Grounded in four cross-cutting themes--equity, high expectations, efficacy, and facilitation from discussion to action--the PLC+ framework supports educators in questioning practices, not just outcomes. It broadens the focus on student learning to encompass educational equity and teaching efficacy, and, in doing so, it leads educators to plan and implement PLCs that maximize individual expertise while harnessing the power of collaborative efficacy.
