Summary:
Berlin School District, located in the town of Berlin, Connecticut, is served by a single high school — Berlin High School — which enrolls 836 students across grades 9 through 12. Berlin High School is a strong academic performer, consistently earning a 4-star rating from SchoolDigger and ranking in the top quartile of Connecticut high schools for three consecutive years. The school was ranked 31st out of 133 high schools statewide in 2025-2026, placing it in the 77th percentile, and has held 4-star ratings each year since 2023-2024.
Academically, Berlin High School significantly outperforms state averages across all tested subjects. In 2025-2026, 71.8% of 11th graders met proficiency on the SAT ELA exam, compared to 55.3% statewide, while science proficiency reached 71.9% versus 50.5% statewide. Math proficiency, while the school's relative weak point, still topped the state at 43.1% compared to 31.3% statewide. The graduation rate is exceptionally high at 97.5%, well above the state average of 91.2%. The school also saw strong year-over-year improvement in math, jumping from 35.3% to 43.1% proficiency.
Despite these strong outcomes, chronic absenteeism stands out as a concern: 22.0% of students are chronically absent, far exceeding the district rate of 14.7% and the state rate of 16.4%. This means more than one in five students misses significant school time, yet the school continues to achieve impressive results. With a student-teacher ratio of 11.5 to 1, students benefit from relatively small class sizes, and about 22.6% of students qualify for free or reduced-price lunch, reflecting a moderately diverse economic background. If Berlin High School can reduce chronic absenteeism, it may further strengthen its already strong academic standing.
