States are under pressure to strengthen literacy and numeracy and close persistent opportunity gaps during ongoing educator workforce instability. Recent evidence from Texas’ Model Professional Learning Community (PLC) at Work® programs – in which educators work collaboratively to achieve better results for their students – suggest that sustained teacher collaboration may be one important part of that effort. This showed stronger academic growth than similar peers in comparable schools. Students experienced gains equal to about 3.1 additional months of learning in math and about two months of learning in reading by the third year of implementation. Gains were especially strong for students facing economic disadvantages and English learners, which could point to the value of long-term school-wide improvement structures through the work of professional learning communities.
Why Model PLC at Work® Schools
Model PLC at Work® schools are important in this analysis because the designation signals sustained implementation over a multi-year period: campuses must document three years of collaboration practices and student growth. That makes these schools a useful way to study whether long-term professional collaboration is associated with student outcomes. In practice, that means educators work in recurring cycles of collective inquiry, data-driven instruction and timely intervention to support student learning.
What State Leaders May Take From These Findings
The findings may be especially relevant for state leaders focused on school improvement and closing opportunity gaps. The results were not limited to a single grade span or subgroup. Students in these schools experienced stronger growth in elementary and middle grades, and the gains became larger over time, suggesting that the academic benefits of structured, collaborative practices may deepen as schools build stronger routines for instruction, data use and intervention.
In Texas, the strongest gains were observed among students facing economic disadvantage in math and English learners in reading. This pattern suggests that sustained educator collaboration may be particularly important in schools serving students with the greatest academic needs.
For leaders, three takeaways stand out:
- Sustained educator collaboration appears to matter most when it is embedded over multiple years rather than treated as a short-term initiative.
- The strongest gains were observed among student groups with some of the greatest academic needs, including students facing economic disadvantages students and English learners. This suggests that teacher collaboration may strengthen educators’ ability to recognize where students need support and respond with timely intervention.
- School improvement structures may influence not only student achievement, but also the professional conditions that support educator growth and retention.
All three findings point to the idea that school improvement may be strongest when collaboration is built into the everyday work of teaching through professional learning communities.
Evidence in Texas also found lower teacher turnover in Model PLC at Work® schools and stronger retention of highly effective teachers, suggesting that sustained collaborative structures may matter not only for student learning, but also for workforce stability and teacher development. For state leaders throughout the country, the message is less about a single program and more about the conditions that make improvement possible. Here in Texas, these findings point to a broader lesson for school improvement.
