This document outlines the key characteristics of a professional learning community (PLC). It discusses how a PLC focuses on student learning through collaborative teams who work interdependently and are mutually accountable. It also emphasizes that a PLC takes an action-oriented approach through continuous cycles of gathering evidence, developing and implementing strategies, analyzing their impact, and applying lessons learned to further improve student outcomes. Finally, it notes that organizations should begin the work of a PLC by taking action, rather than solely preparing through reading or training, in order to more effectively help all students learn at high levels.
