Summary:
The city of Unionville, Connecticut, is served by two public elementary schools — West District School (grades K–5) and Union School (grades K–4) — both part of the highly rated Farmington School District, which ranks in the top 12% of Connecticut districts. There are no middle or high schools in Unionville itself, so this analysis focuses on elementary performance.
West District School is the clear standout, ranking 11th among 491 Connecticut elementary schools (98th percentile, 5 stars) for 2025–2026. It outperforms both Union School and the district in nearly every SBAC subject and grade. Its math scores are exceptional: 89.2% of 3rd graders and 90.5% of 4th graders are proficient, roughly 38 points above state averages. West District also improved dramatically from last year, with 4th grade math jumping from 76.8% to 90.5% and 4th grade ELA from 73.9% to 84.5%. Union School, while still well above state averages, ranks 79th (84th percentile, 4 stars) and trails West District by about 10 percentage points in combined proficiency. Union falls below its district average in three of four 2025–2026 test categories, with only 4th grade ELA (81.5%) exceeding the district mark. Union’s 3rd grade ELA dipped from 73.1% to 66.7%, though its 4th grade math improved by 10.2 points.
Interestingly, Union School actually looks better on non-test metrics: it has lower chronic absenteeism (2.9% vs. 4.0%), a lower student–teacher ratio (11.3 vs. 12.2), and higher spending per student ($16,970 vs. $15,871). Yet West District still posts far stronger academic results. Union also has a higher free/reduced lunch rate (23.6% vs. 16.5%), a factor that often correlates with achievement. Both schools improved their statewide rankings this year, and both have very low chronic absenteeism, reflecting strong engagement. For parents, the bottom line is that Unionville offers two solid, above-average elementary schools — with West District firmly in the state’s elite tier and Union School a dependable choice that remains comfortably ahead of Connecticut averages.
