Summary

R. Dudley Seymour School is a small, highly regarded elementary school in East Granby, CT, serving 191 students in grades 3–5 as part of the East Granby School District. The school currently ranks 108th out of 491 Connecticut elementary schools, placing it in the 78th percentile with a 4-star rating — a strong improvement from its 192nd-place ranking in 2020–2021. Students consistently outperform state averages in English language arts, mathematics, and science, and the school's chronic absenteeism rate of just 6.2% is roughly one-third the state average, pointing to a highly engaged and supportive school community.

Compared to nearby schools, R. Dudley Seymour stands out. It outperforms Wells Road Intermediate School in Granby on nearly every reported test — for example, 72.7% vs. 61.4% in 5th grade ELA and 73.0% vs. 51.8% in 3rd grade math for 2025–2026 — despite similar poverty rates. Science is a particular strength, with 5th grade proficiency at 74.2% versus the state average of 52.9%. Within a five-mile radius, only Central School and Squadron Line School in Simsbury rank higher. The school also benefits from a favorable 13.2:1 student-teacher ratio and higher per-pupil spending ($18,465) than nearby Granby schools.

The clearest area for improvement is upper-elementary math. While 3rd grade math proficiency is strong at 73.0%, it drops to 57.6% by 5th grade — a pattern that has persisted across multiple years. Because the school is small, individual grade cohorts can cause year-to-year swings, so these numbers should be read with some caution. Overall, R. Dudley Seymour's combination of strong test scores, very low absenteeism, and a well-resourced environment makes it one of the strongest elementary options in the region outside the top-tier Simsbury schools.
