Best Public Schools in Zip Code 06405

ZIP code 06405 is served by five schools in the Branford School District: three elementary schools (Mary R. Tisko School, Mary T. Murphy School, John B. Sliney School), one middle school (Francis Walsh Intermediate School), and one high school (Branford High School), enrolling 2,448 students combined. The district overall ranks in the middle of Connecticut districts, but the schools within it vary widely, and families will find meaningful differences depending on which school their child attends.

The clear standout is Mary R. Tisko School, a 4-star elementary school ranking in the 81st percentile statewide. Tisko posts the strongest test scores in the district, the lowest chronic absenteeism (4.6%), and the lowest poverty rate. By contrast, Mary T. Murphy School and John B. Sliney School are 3-star schools with higher poverty rates and more modest proficiency levels. Francis Walsh Intermediate School, the feeder middle school, ranks above the district average and starts strong in 5th grade but declines by 8th grade. Branford High School has a strong 93.1% graduation rate but the highest chronic absenteeism in the ZIP code at 14.1%.

Several findings stand out. Tisko's improvement is notable, jumping from the 69th to 81st percentile over two years. Test scores track closely with free/reduced lunch rates, suggesting socioeconomic factors drive much of the variation. Walsh's grade-level decline — from 73.2% ELA proficiency in 5th grade to 50.0% in 8th grade — is a concern. Meanwhile, higher spending and smaller class sizes do not reliably produce better outcomes; John B. Sliney School has the lowest student-teacher ratio but not the highest scores. Overall, 06405 offers one high-performing elementary school, a middle school that fades, and a high school with solid graduation rates but attendance challenges. Note that data gaps exist: Branford High School lacks current test data and spending figures are from 2018–2019.
