Summary:
Zip code 06066 is served by a single public high school — Rockville High School — which enrolls nearly 1,000 students in grades 9–12 and is part of the Vernon School District. With only one high school serving this area, there is no within-zip comparison; instead, the school is best evaluated against its district and state averages. Rockville High School mirrors its district almost exactly in academic performance, with test scores in English language arts, math, and science differing from district figures by less than one percentage point. However, in every subject, the school trails Connecticut state averages. It has consistently earned a 2-star rating from SchoolDigger, ranking in the lower-middle range of high schools statewide (40th percentile in 2024–2025).
Academically, math is the most significant concern: just 23.8% of 11th graders scored proficient on SAT math, more than 7 points below the state average of 31.1%. English language arts proficiency (48.9%) is closer to the state average (58.0%) but still trails by roughly 9 points. Science shows more promise, with NGSS proficiency improving substantially from 31.7% to 40.0% year over year, though it remains about 10 points below the state average.
On non-test measures, the school shows notable strengths. Its graduation rate of 90.5% matches the district average and sits just 0.7 points below the state. Chronic absenteeism is 13.4% — better than the state rate of 16.4% — which is impressive given that more than half of the students (52.56%) qualify for free or reduced-price lunch. The school also benefits from a favorable 12.1:1 student-teacher ratio. While the recent dip in statewide percentile ranking and low math proficiency are worth watching, Rockville High School remains a solid, representative high school for the Vernon community, with encouraging momentum in science and attendance.
