Evidence of Effectiveness

Professional learning communities (PLCs) are a teacher collaboration and professional development strategy that is widely used in public schools in the United States and beyond. PLCs have the potential to improve instruction and student learning through structured, ongoing, job-embedded staff collaboration. However, many schools find it challenging to implement the features of PLCs effectively. The Arkansas Division of Elementary and Secondary Education (DESE) invested in three years of intensive supports for schools to build high-functioning PLCs using Solution Tree’s Professional Learning Communities at Work® (PLC at Work®) model.

The findings in the research developed by Education Northwest are relevant for schools considering or actively using PLCs to improve collaboration, teaching, and learning. For more information on the independent evaluation of PLC at Work in Arkansas, please contact: Kathryn Torres, Ph.D., Principal Investigator at [email protected] or Jennifer Esswein, Ph.D. at [email protected].
