Summary:
ZIP code 06043 is home to one high school, Bolton High School, a small public school serving grades 9–12 in Bolton, CT, within the Bolton School District. With just 212 students, this single-high-school district offers a highly personalized learning environment, reflected in an unusually low student-teacher ratio of 7.4:1. Bolton High School stands out as a strong academic performer: its graduation rate is an exceptional 97.9%, well above the state average of 91.2%, and its SAT English Language Arts proficiency rates of 67.4% (2025–26) and 76.6% (2024–25) both easily surpass state averages. The school also keeps chronic absenteeism at 11.3%, notably better than the state's 16.4% showing.
Bolton High School has demonstrated a steady upward trajectory in its state ranking, improving from the 74th percentile (52nd of 200 schools) in 2020–21 to the 86th percentile (20th of 145 schools) in 2023–24, earning consistent 4-star ratings. While the district as a whole ranks in the 63rd percentile (57th of 153 districts), the high school's own performance is substantially stronger, suggesting that the district ranking is tempered by other factors or schools. About 27.36% of students qualify for free or reduced lunch, yet the school continues to deliver strong academic outcomes despite this moderate level of economic disadvantage, and per-student spending is high at $23,195.
Families should note a few watch points: SAT ELA proficiency dropped 9.2 percentage points year over year (from 76.6% to 67.4%), a steeper decline than the state's 2.7-point dip, though the school remains well above average. Additionally, the school's chronic absenteeism rate of 11.3% is higher than the district-wide rate of 7.2%, meaning some Bolton High students miss more school than their peers in the district. Overall, Bolton High School presents a compelling picture: a small, well-funded school with near-perfect graduation rates, strong test scores, improving rankings, and a supportive environment—making it an excellent option for families in the 06043 area.
