Summary:
Zip code 06013 (Burlington, Connecticut) is served by a single middle school, Har-Bur Middle School, which enrolls 669 students in grades 5 through 8 and belongs to Regional School District 10. This one-school district area means all middle-level results in the zip come from Har-Bur, and those results are consistently strong.
Har-Bur is a high-achieving school that earns a 4-star rating from SchoolDigger and ranks in the top quarter of Connecticut middle schools—56th out of 258 schools in the 2025-2026 school year, placing it in the 78th percentile statewide. Its students far exceed state averages in every subject: 67.9% are proficient in English language arts versus 52.0% statewide, 57.0% in math versus 44.1%, and 67.0% in science versus 51.9%. The school also posts an exceptionally low chronic absenteeism rate of 4.8%, compared to 16.4% for the state, and benefits from a favorable 11.6-to-1 student-teacher ratio. However, performance is not uniform across grade levels: 6th and 8th graders improved from the prior year in both ELA and math, while 5th and 7th graders saw declines. The lowest area is 7th grade math at 52.2%, a drop from 59.8% the year before, and 5th grade science dipped slightly as well.
With only 17.79% of students eligible for free/reduced lunch, Har-Bur serves a predominantly higher-income population, a useful context when comparing its results to schools with more poverty. Because Har-Bur is the only middle school in the zip code, no intra-zip comparison is possible; instead, the school’s performance should be viewed against state and district benchmarks. Overall, Har-Bur Middle School presents a very positive picture: top-quartile rankings, wide margins above state proficiency, and excellent attendance. Parents in Burlington can expect a stable, well-supported middle school environment, with the main watch items being 7th grade math and the recent 5th grade declines.
