Summary

Union School is a small K-4 elementary school in Unionville, CT, serving 305 students as part of the highly regarded Farmington School District, which ranks in the top 12% of Connecticut districts. The school earns a 4-star rating and ranks 79th out of 491 elementary schools statewide (84th percentile), with academic performance well above state averages: 66.7% of 3rd graders and 81.5% of 4th graders scored proficient in ELA, compared with state averages of 47.3% and 50.9%, while math proficiency reached 73.6% and 76.9% versus state averages around 52%.

Union stands out for exceptionally low chronic absenteeism (2.9% versus a 16.4% state average), a low student-teacher ratio of 11.3:1, and high per-pupil spending of $16,970. It outperforms most non-Farmington neighbors by wide margins — for example, 4th grade ELA proficiency of 81.5% far exceeds Mountain View School's 58.3% and Louis Toffolon School's 62.7%. Within its own district, however, Union trails West District School (ranked 11th) and Noah Wallace School (ranked 61st) in most subjects, despite having lower absenteeism and more resources — a gap that suggests school-level differences beyond attendance and spending. Union's 4th grade math (76.9%) does beat several Avon-area schools like Pine Grove School (68.8%) and Roaring Brook School (71.8%).

One notable trend is a growing gender gap: female students rank 13th of 225 schools statewide (94th percentile, 5 stars), while male students have slipped to 82nd of 232 (65th percentile, 3 stars) — a significant divergence worth investigating. The school has also shown upward momentum overall, improving from a rank of 190th in 2017-2018 to 79th in 2025-2026, and maintaining a top-20% position since 2020-2021. With strong attendance, small classes, and solid test scores, Union School is a strong choice for families within a top-ranked district, though parents may want to ask about how the school supports male students and math instruction relative to its closest district peers.
