Best Public Schools in Zip Code 06401

Zip code 06401 in Ansonia, Connecticut, has five schools—two elementary, one middle, and two high schools—serving about 2,961 students across two districts: the Ansonia School District and the Connecticut Technical Education and Career System. The Ansonia School District ranks 149 out of 153 districts in Connecticut (3rd percentile), among the lowest-performing in the state, while the Connecticut Technical Education and Career System ranks 139 out of 153 (9th percentile). Free/reduced-price lunch eligibility ranges from 43.7% at Emmett O'Brien Technical High School to 66.6% at Mead School, indicating a predominantly economically disadvantaged student population.

The clearest standout is Emmett O'Brien Technical High School, with a 96.7% graduation rate—well above the state average of 91.2% and far better than Ansonia High School's 83.1%. It also holds the highest high school rank in the zip (102 out of 133) and the strongest ELA and science scores among the area's high schools. At the elementary level, Mead School is the top-ranked in the zip at 388 out of 491 schools, and posted the highest single-grade math proficiency in the zip—41.6% of 4th graders proficient in math versus just 23.1% at Prendergast School. On the other end, Ansonia Middle School is the biggest concern: ranked 225 out of 258 middle schools with 21.9% chronic absenteeism.

Across nearly every metric, these schools trail Connecticut state averages. High school math proficiency sits in the single digits (7.3% at Emmett O'Brien Technical High School and 9.9% at Ansonia High School), and middle school math proficiency declines from 18.1% in 6th grade to 12.4% in 8th grade. Chronic absenteeism is especially severe at Ansonia Middle School, where more than 1 in 5 students are chronically absent. Notably, Ansonia High School spends the most per student at $19,054, yet its graduation rate and test scores remain low relative to the state. These patterns point to systemic challenges in math instruction, attendance, and support for economically disadvantaged students across the feeder pathway, though Prendergast School's 13.5% chronic absenteeism and Emmett O'Brien Technical High School's strong graduation rate are modest bright spots.
