It’s often said that Professional Learning Groups (AKA Professional Learning Communities or Critical Friends Groups) are a vital component of school reform efforts, but what does it really take to implement and support Professional Learning Groups (PLGs) in a way that actually impacts teacher practice and student achievement? We will define the non-negotiables of effective PLGs, examine best practices for training and supporting facilitators, and consider what we must do to make PLGs something more than another meeting time. We will share resources, talk through scenarios, and provide a structure for both teachers and administrators to begin designing or improving PLGs at your school.
