Summary:
ZIP code 37027 in Brentwood, Tennessee, is served by 14 schools—9 elementary, 3 middle, and 2 high schools—enrolling about 11,966 students, and it is home to an extraordinary concentration of top-ranked public schools. Most of these schools belong to Williamson County Schools, the #3 district in Tennessee, but Granbery Elementary School sits in the same ZIP code while belonging to Metro Nashville Public Schools, a district ranked #126. This district split matters enormously: Granbery’s math proficiency is 53.5%, while the Williamson County elementary average in this ZIP code is 83.3%—a nearly 30-point gap between schools just minutes apart.
The Williamson County schools here are among the best in Tennessee. Woodland Middle School ranks #2 statewide, Brentwood Middle School ranks #3, and Lipscomb Elementary School ranks #6. Grassland Elementary School is a rising star, climbing from #33 to #10 in three years, with the area’s highest elementary ELA score at 88.1%. At the high school level, Ravenwood High School ranks #7 and excels in Algebra II and Biology I, while Brentwood High School ranks #16 with the highest graduation rate in the ZIP code at 98.4% and a standout English II proficiency of 93.1%.
Even the “lower-performing” Williamson elementary schools rank in the 94th–95th percentile statewide, so nearly every school in 37027 offers strong academics. Still, there are useful distinctions: Ravenwood High has the higher state ranking, but its chronic absenteeism rate of 13.1% is more than double Brentwood High’s 5.9%. Both high schools show Algebra I as their relative weak point, despite very strong Algebra II and geometry scores. Spending per student does not predict performance—Granbery Elementary spends the most at $15,786 yet has the lowest scores, while Ravenwood High spends the least at $11,246 and ranks near the top. For parents, the key takeaway is that address alone is not enough: district assignment and school-specific strengths matter far more than ZIP code.
