Summary:
Zip code 06339 in Connecticut is served by a single public high school, Ledyard High School, which enrolls 731 students in grades 9 through 12 as part of the Ledyard School District. This makes the analysis a focused look at one school, and Ledyard High School stands out most strongly for its excellent graduation rate of 96.6%, which comfortably outpaces the state average of 91.2%, as well as for notable strengths and some clear areas of concern.
Academically, Ledyard High School is a mixed picture. In the 2025-2026 school year, 11th graders posted strong proficiency rates in English Language Arts (64.9%) and Science (62.7%), both well above the Connecticut state averages of 55.3% and 50.5%. However, math proficiency is a persistent weak spot: only 28.7% of students were proficient, falling below the state average of 31.3%. The school also saw steep year-over-year declines in both ELA and math scores from the prior year, with ELA dropping by 13.7 percentage points and math by 9.5 points. State ranking has fluctuated, moving from the 57th percentile in 2023-2024 to the 74th in 2024-2025, and settling at the 65th percentile in 2025-2026.
One red flag for parents is chronic absenteeism. At 23.7%, Ledyard High School’s rate is nearly 1.7 times higher than the district average (14.0%) and well above the state rate (16.4%). This is especially noteworthy given that the school otherwise shows strong student persistence and high graduation rates. On the positive side, the school benefits from a favorable student-teacher ratio of 11.4:1 and relatively high per-student spending of $16,699, yet these resources have not translated into stronger math achievement. Since this is the only high school in the area, these trends define the local educational experience, so families should weigh the school’s impressive graduation and literacy/science outcomes against its math challenges and absenteeism concerns.
