Best Middle Schools in Zip Code 06370

There is one middle school serving zip code 06370 in Oakdale, CT: Leonard J. Tyl Middle School, part of the Montville School District. The school serves grades 6 through 8 with an enrollment of 519 students, and because it is the only middle school in this area, there are no direct school-to-school comparisons to make — the school's results essentially mirror the district's middle school performance.

Leonard J. Tyl shows several strengths. In 2025–2026, 6th graders beat the state average in both ELA (52.5% vs. 51.2%) and math (48.4% vs. 44.4%). The school also posted a strong 8th grade science result, with 55.9% proficient compared to 50.9% statewide, a 6.7-point improvement over the prior year. The student-teacher ratio is a favorable 11.5:1, and the school's state percentile rank has ticked upward over three years, from the 46th to the 49th percentile. About 46.4% of students qualify for free or reduced-price lunch, and 16.9% are chronically absent, slightly above the state average of 16.4%.

The main concerns are in the later grades. 7th grade math proficiency is only 28.6%, a 15.5-point gap below the state average, and 8th grade ELA trails the state by 5.7 points. Math results also moved in opposite directions across grades year over year: 6th grade math jumped 11.5 points, while 7th and 8th grade math declined by 4.5 and 5.2 points, respectively. The school has maintained a 2-star rating from SchoolDigger and ranks in the lower half of Connecticut middle schools, though its slow upward trend is encouraging. With per-student spending of $17,826, the school allocates significant resources, but 7th grade math, 8th grade ELA, and chronic absenteeism are the areas most worth watching and most likely to benefit from targeted intervention.
