Summary:
Lebanon, Connecticut, is served by a single high school — Lyman Memorial High School — which teaches students in grades 9 through 12 within the Lebanon School District. With an enrollment of just 322 students, this is a small, close-knit school, and any analysis of "Lebanon high schools" is really a detailed look at this one institution rather than a comparison among competing schools.
Lyman Memorial High School's strengths are clear. Its 94.9% graduation rate beats the state average of 91.2%, and its science proficiency (53.6% of 11th graders) also edges out the state (50.5%). The school maintains a very low student-teacher ratio of 8.8, backed by per-student spending of $22,645, which typically means smaller classes and more individualized support. About 28% of students qualify for free or reduced lunch, yet the school still posts these strong results. Lyman has earned a solid 3-star rating from SchoolDigger, and the Lebanon School District itself ranks 65th out of 153 districts statewide, placing it in the 58th percentile.
The biggest concern is chronic absenteeism. At 18.1%, Lyman Memorial High School's rate is well above the district's 11.9% and the state's 16.4%, which suggests some students are disengaged even as the majority go on to graduate. Also worth watching: the school's state percentile ranking has declined from the 66th percentile in 2020–2021 to the 54th percentile in 2023–2024, though it has consistently maintained its 3-star rating. For parents, this is a well-resourced, small high school with above-average graduation and science outcomes, personalized attention, and competitive per-student investment — with attendance being the main area to monitor.
