Best Public Schools in Zip Code 06234

In zip code 06234, which covers Brooklyn, Connecticut, two public schools serve students from pre-kindergarten through 8th grade under the Brooklyn School District. Brooklyn Elementary School enrolls 469 students in grades PK–4, while Brooklyn Middle School serves 373 students in grades 5–8; there is no high school in this zip code, so families must plan for high school elsewhere.

Brooklyn Middle School is the clear standout. It ranks in the 62nd percentile of Connecticut middle schools (3 stars) with strong English Language Arts and science scores. In 2025–2026, its ELA proficiency topped the state average in every grade level, and science proficiency was roughly 10 points above the state average in both 5th and 8th grades. Chronic absenteeism is just 6.4%, far below the district and state averages. By contrast, Brooklyn Elementary School is slipping: its ranking fell from the 54th percentile (3 stars) in 2023–2024 to the 40th percentile (2 stars) in 2025–2026. The elementary school's 4th-grade ELA proficiency dropped from 50.0% to 35.7%, and 4th-grade math fell from 63.0% to 47.6% year-over-year. While 3rd-grade math remains above the state average, both 3rd and 4th grade ELA now trail the state.

Key differences explain the gap. The middle school has a lower share of students eligible for free/reduced lunch (36.7% vs. 43.5%), a lower student-teacher ratio (10.8 vs. 11.7), and higher per-student spending ($15,751 vs. $13,107). The elementary school's chronic absenteeism rate (11.7%) is higher than the middle school's (6.4%), although still below the state's 16.4%. One red flag at the middle school is 6th-grade math, which fell 20.1 points to 30.4% proficiency—14 points below the state average—even as other grades improved or held strong. Overall, the district's 2-star rating masks the middle school's success, and the elementary school is clearly the area needing the most attention.
