A PLC is a collaborative team of educators who meet weekly to clarify essential learning standards that all students must learn, monitor student progress frequently through common formative assessments, and respond with timely, systematic support. Teams ensure that students who struggle receive additional time and help, while students who have mastered skills are extended and enriched. PLCs celebrate student growth and evaluate their work based on results rather than intentions, with the shared goal of ensuring high levels of learning for all students.
