Summary:
The Montville School District is served by a single middle school, Leonard J. Tyl Middle School in Oakdale, CT, which enrolls 519 students in grades 6–8. The school has a favorable 11.5:1 student-teacher ratio and a free/reduced-price lunch rate of 46.4%, reflecting meaningful economic diversity. Chronic absenteeism (16.9%) is essentially in line with the state average (16.4%). The district itself ranks 104th out of 153 Connecticut districts, placing it in the lower third statewide, though the school's individual rank sits much closer to the median, at the 48th–49th percentile over the past three years.
Performance is uneven across grades and subjects. The most pressing concern is 7th grade math, where only 28.6% of students are proficient, a staggering 15.5 points below the state average — and this has been a persistent gap for two consecutive years. By contrast, 6th grade math improved dramatically, jumping from 36.9% to 48.4% proficiency, now 4 points above the state. Eighth grade science is the school's clearest strength at 55.9% proficiency, 5 points above the state. English language arts follows a consistent pattern: 6th graders perform at the state average, but proficiency drops in 7th and 8th grades by roughly 6 points each year. Statewide, the school has remained flat in percentile, moving only from 46th to 49th, meaning scores are improving at about the same pace as other schools.
Across all grades, the school averages 48.1% in ELA and 38.2% in math for 2025–2026, with combined subject averages showing modest year-over-year gains, including a strong 6.7-point jump in science. The low student-teacher ratio and per-pupil spending of $17,826 are positive structural signals. Overall, this is a solidly middle-performing school that handles significant demographic challenges while producing notable bright spots in 6th grade math and 8th grade science, though a sustained focus on 7th grade math will be critical to improving its statewide standing.
