Summary:
Zip code 06238 in Coventry, Connecticut, is served by two elementary schools in the Coventry School District, a highly rated 4-star district ranked 42nd out of 153 in the state; together, Coventry Grammar School (grades K–2) and George Hersey Robertson School (grades 3–5) enroll roughly 731 students and form a clean feeder pipeline from primary through upper elementary.
George Hersey Robertson School is the clear academic standout, with students scoring far above Connecticut averages in every tested subject and grade level. In 2025–2026, 5th-grade math proficiency reached 76.2% versus the state's 45.8%, 5th-grade science hit 79.5% versus 52.9%, and 4th-grade ELA reached 78.0% versus 50.9%. The school has ranked in the top quarter of Connecticut elementary schools for three straight years (74th–77th percentile) and posts an exceptionally low 3.2% chronic absenteeism rate. Coventry Grammar School, while lacking test data due to its K–2 span, stands out for investing $18,106 per pupil—about 26% more than Robertson's $14,329—and maintaining a low 12.3 student-teacher ratio, suggesting a strong early-education foundation despite serving a slightly higher percentage of economically disadvantaged students (31.3% vs. 26.5%).
Both schools dramatically outperform the state on attendance: chronic absenteeism is 3.2% at Robertson and 5.6% at Coventry Grammar, versus 16.4% statewide. The main concern is a sharp 17.1-point drop in 3rd-grade ELA proficiency at Robertson, from 67.5% in 2024–2025 to 50.4% in 2025–2026, while 4th- and 5th-grade ELA remain strong (78.0% and 77.8%), and 3rd-grade math stayed stable. Additionally, 5th-grade math dipped from 81.4% to 76.2%, and the school's state percentile slipped slightly. The district should monitor these trends, but overall the data paints a picture of a stable, well-resourced, high-performing elementary pairing.
