Summary:
ZIP code 37046 (College Grove, TN) contains just one public school, College Grove Elementary School, a K–5 school that is part of the highly ranked Williamson County Schools district. Because there is no middle or high school within the ZIP code, families in College Grove rely on this single elementary school before leaving the immediate area for secondary education.
College Grove Elementary is an elite school not just locally, but across Tennessee. It has ranked in the top 3% of elementary schools statewide for three straight years, including #25 out of 1,019 in 2025–2026. The school outperforms its already excellent district and roughly doubles the state average in every subject: 85% proficiency in math, 75.6% in English language arts, and 79.8% in science. Its strongest areas are 4th grade math (87.7%), 3rd grade ELA (83.3%), and 4th grade science (82.5%). The one relative weakness is 5th grade ELA at 65.3%, the only tested grade and subject where the school falls below its district average, though it remains well above the state average.
Year-over-year trends show math improving by 2.7 points, while science dropped sharply from 85.9% to 79.8% — the biggest decline to watch. ELA dipped slightly but stayed above the district. The school also benefits from strong attendance, with a 7.1% chronic absenteeism rate nearly matching the district’s 7.4% and far better than the state’s 18.3%. Per-student spending is substantial at $15,645, reflecting the significant investment common in Williamson County. Overall, College Grove Elementary is a standout school in a top-ranked district, delivering exceptional academic results with only a couple of areas — 5th grade literacy and recent science performance — worth monitoring.
