Across all grade levels, subject areas, and socioeconomic contexts in Texas,
Model PLC at Work® Schools outperformed statewide averages

The report

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.

The results

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.

Plus, consistently lower teacher turnover than statewide averages

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.
