Texas Tech University’s Center for Innovative Research in Change, Leadership, and Education (CIRCLE) recently completed a three-part report that examined the characteristics of Model Professional Learning Communities (PLC) at Work® schools in Texas, compared their academic growth over time to state averages and matched schools, and evaluated how PLC at Work has impacted teacher retention.
Students in Model PLC at Work schools consistently demonstrated higher academic achievement compared to statewide averages. Math proficiency rates exceeded state averages by 5 to 8 percentage points, reading/language arts (RLA) proficiency surpassed state benchmarks by 4 to 12 percentage points, and science proficiency was approximately 8 to 9 percentage points higher. Additionally, teacher turnover was lower relative to state averages, and Highly Effective Teachers (top quartile of value-added measures) were more likely to stay.
These results reflect the effectiveness of the PLC at Work process in raising student performance and improving academic outcomes—and increasing overall stability in teacher retention. The consistency gains highlight the impact of collaborative teaching practices and a strong focus on learning within high-performing PLC schools.

Turnover in Model PLC Schools is consistently lower than statewide averages, suggesting that the PLC at Work process creates organizational cultures that already support higher-than-average teacher stability.”

Teacher turnover disrupts students and their learning process, so increased teacher retention means greater student success.

In addition, highly effective teachers were more likely to stay in Model PLC at Work schools, while turnover modestly increased among less effective teachers.

Solution Tree, a professional learning company that provides research-based, results-driven services, offers the Professional Learning Communities (PLC) at Work process. PLC at Work is a cyclical, data-driven process that empowers educators to engage in collective inquiry and action research for better student results. It is designed to foster a culture of collaboration, a focus on learning, and student-centered, results-oriented decision-making. Schools and districts may apply for Model PLC at Work designation, which recognizes exemplary implementation of the PLC at Work process and at least three years of measurable improvements in student achievement.
