Schools in Zip Code 37032

Zip code 37032, covering Cedar Hill, TN, is served by two public schools—Jo Byrns High School (grades 6–12) and Jo Byrns Elementary School (grades PK–5)—with a combined enrollment of 882 students under Robertson County Schools, a district ranked in the lower tier of Tennessee.

Jo Byrns Elementary School is the clear academic standout in the area. It outperforms its district in every major subject, with all-grades math proficiency at 44.1% and science at 42.3%, both above district averages. Its 4th grade math proficiency of 56.7% exceeds the state average, and chronic absenteeism is remarkably low at 10.6%. By contrast, Jo Byrns High School shows mixed performance: overall proficiency is low in math (20.0%), ELA (15.9%), and social studies (24.2%), but it excels in Biology I (50.0%) and English II (56.5%). The high school also posts strong graduation outcomes—a 94.4% graduation rate and just a 1.4% dropout rate, both far better than the district and state.

The most concerning trend is the advanced math gap at the high school: 8th grade Algebra I proficiency is just 31.8% versus 88.3% statewide, and 9th grade Geometry proficiency is 30.4% versus 87.9% statewide. Middle-grade subjects are also weak, with 7th grade ELA proficiency at 13.2% and science at 11.8%. The lack of a standalone middle school means 6th–8th graders learn in a high school setting, which may contribute to these struggles. Additionally, year-to-year score swings at the high school are dramatic—Biology I jumped 24.6 points and English II 28.4 points in one year—suggesting inconsistent instruction. Notably, Jo Byrns Elementary School spends $17,151 per student, about $3,500 more than the high school, and its stronger results suggest that investment is paying off.
