Summary:

Zip code 06489 in Southington, Connecticut is served by a single high school — Southington High School — which enrolls 1,905 students in grades 9–12 as part of the Southington School District. With no other high school in the zip code for direct comparison, the school is best evaluated against district and state averages, and it measures up well. Southington High School has earned a 4-star SchoolDigger rating for three straight years, currently ranks 35th out of 133 Connecticut high schools (74th percentile), and posts a 96.0% graduation rate that exceeds both the district (95.1%) and state (91.2%) figures.

Academically, 11th graders at Southington High School outperform state averages in every tested subject. In 2025–2026, 66.7% were proficient in English Language Arts on the SAT — 11 points above the state — while science proficiency reached 68.7%, a full 18 points above the state average of 50.5%. Math, however, lagged at 39.8% proficiency. Although that was 8 points above the state average, it sat far below the school's own ELA and science numbers, creating a roughly 27-point gap between math and ELA and an even larger gap versus science. The school also maintains a favorable 12.7:1 student-teacher ratio, with 25.67% of students eligible for free or reduced-price lunch.

The clearest takeaway for parents is that math is Southington High School's primary weakness. Proficiency inched up from 37.1% to 39.8% year-over-year, but the gap between math and the school's other subjects remains substantial. Meanwhile, ELA proficiency slipped from 70.5% to 66.7%, and science held steady at 68.7%, which stands as the school's strongest subject relative to state benchmarks. Chronic absenteeism of 14.3% runs above the district's 11.1% but below the state's 16.4%, and it hasn't kept the school from graduating 96% of its students. Overall, Southington High School is a reliable, above-average option with consistent rankings and strong outcomes, and addressing the math gap would be the biggest lever for further improvement.
