Summary:
Zip code 37073 is served by one elementary school, Greenbrier Elementary School, which enrolls 600 students in grades PK–5 as part of Robertson County Schools. Because only one school is listed in the area, the most useful comparisons are to the district and state benchmarks, and on those measures Greenbrier stands out as a clear academic leader within a district that overall ranks in the bottom third of Tennessee.
Greenbrier Elementary outperforms both its district and the state in every TNReady subject area. In the most recent school year, math proficiency reached 50.5% (compared to 38.8% district and 43.0% state), ELA reached 48.3% (vs. 35.8% and 40.6%), and science reached 50.9% (vs. 38.7% and 46.9%). The school’s strongest grade-level results include 4th grade science at 54.8% proficient, 5th grade math at 53.2%, and 4th grade ELA at 51.9%. Its only relative weak spot is 5th grade ELA at 44.6%, though that is still above both the district (38.0%) and state (42.7%). The school also posts a notably low chronic absenteeism rate of 11.6%, far better than the district’s 15.5% and the state’s 18.3%—a positive sign for consistent learning.
One cautionary trend: Greenbrier’s state ranking has declined steadily, from the 79th percentile in 2023–2024 to the 66th percentile in 2025–2026, and its star rating has dropped from 4 stars to 3. Proficiency rates have also slipped over the past year, with math down 4.8 points, ELA down 2.7 points, and science down 2.1 points. Even with that decline, the school remains above state averages in all subjects and serves as a strong option for families in the 37073 area. With one school in the zip code, Greenbrier Elementary is automatically the top performer locally and a solid choice relative to district and state norms.
