This document discusses professional learning communities (PLCs) and their potential to foster collaborative success in schools. It provides historical context for educational reform efforts beginning with A Nation at Risk in 1983 and the No Child Left Behind Act in 2001. The document defines PLCs as groups of educators working collaboratively to improve student outcomes. It reviews research showing that effective PLCs develop high levels of trust among stakeholders and incorporate teacher collaboration, data-driven instruction, administrative support, and community involvement. The document argues that PLCs that demonstrate these characteristics are more likely to achieve measurable gains in student performance.
