Summary:
The Great Oaks Charter School District is a single-school district in Bridgeport, CT, home to Great Oaks Charter School, a combined grades 6–12 high school serving 662 students in a high-poverty urban area. Because the district contains only one school, all district-level and school-level metrics are identical.
Great Oaks Charter School ranks 152nd out of 153 Connecticut districts (1st percentile) and 128th out of 133 high schools (4th percentile) in the most recent rankings, earning 0 stars in every reported year. Academic performance is critically low across every subject: in 2025–2026, only 17.6% of 6th graders and 18.7% of 11th graders were proficient in ELA, compared to roughly 51–55% statewide, while 8th grade math proficiency was just 8.2% versus 41.9% statewide. Science proficiency sits around 23–24%, roughly 27 points below the state. The graduation rate is 77.4% compared to the state's 91.2%, and chronic absenteeism is 26.2% versus 16.4% statewide. About 82% of students qualify for free/reduced lunch, and the student-teacher ratio is 16.9:1. Per-student spending is listed at $14,322 but dates back to 2018–2019, so it should be interpreted cautiously.
Math is the school's weakest area, and the sharp drop in 8th grade math proficiency from 24.0% in 2024–2025 to 8.2% in 2025–2026 is especially concerning. Even so, the school has shown modest improvement in its state rank, moving from the 1st percentile in 2021–2022 to the 4th percentile in 2025–2026, though it remains firmly in the bottom 4% of Connecticut high schools. There are no other schools within the district to benchmark against, so comparisons must be made to state averages — and by every measure, Great Oaks Charter School is severely underperforming. The combination of high economic disadvantage, chronic absenteeism, and low test scores points to a need for intensive intervention in math, attendance, and graduation support.
