Original Research by School Decision on Pomperaug Regional High School
Pomperaug Regional High School is a public high school serving grades 9 through 12 in Southbury, Connecticut, with an enrollment of about a thousand students. It is part of Regional School District 15, which also serves Middlebury and draws from a suburban area with retained rural character, low-density residential neighborhoods on spacious wooded lots, and an active-adult population centered around Heritage Village, the state's largest active-adult retirement community.
The school's most recent state assessment data, from the 2024-25 school year, shows proficiency rates that fall below the midpoint in most subjects. In English language arts and math, the school's proficiency stands at under three-fifths of students. Science proficiency is somewhat stronger but still below two-thirds. State assessment data spanning multiple years was not available, so trends cannot be discerned. The school's graduation rate and chronic absenteeism rate were not reported in the available data, limiting visibility into completion and engagement outcomes. Among districts in the Naugatuck Valley Planning Region, the school's overall proficiency index could not be calculated because figures were missing, preventing a direct comparison to neighboring districts.
The student body is predominantly white, with Asian and Hispanic students each representing smaller shares and other racial and ethnic groups present in modest numbers. A moderate share of students qualify for free or reduced-price lunch, indicating mixed economic circumstances within the enrollment. No data on students with individualized education plans or English learners was available.
Southbury itself is a town in transition. For most of its history it was rural and agricultural, but the opening of Interstate 84 brought suburban development and easier access to Hartford, Danbury, New York, and Waterbury. Today the town blends sprawling rural areas with suburban neighborhoods and a defined commercial center on Main Street South. Walkability is concentrated there, around the Southbury Green and municipal buildings, rather than town-wide; elsewhere the landscape is car-dependent. Growth has slowed considerably from the early 2000s, with the town adopting explicit policy to preserve historic and rural character. New construction is now sparse, averaging fewer than twenty new housing units annually, and is focused on senior and affordable housing. The median home value is above the state benchmark, placing housing costs above the national median as well.
At the district level, two significant changes are reshaping the environment for families. In May 2026, voters approved a substantial bond to replace the two oldest elementary schools in the district, both nearing the end of their useful life. The district is pursuing state construction grants to offset costs, but families should expect this to carry a lasting property-tax impact over time. Additionally, the district has developed and is implementing a competency-based framework called the Portrait of a Learner that is reshaping curriculum and instruction across all grade levels as a multi-year initiative. This shift in pedagogy and assessment philosophy is material for families considering this district.
The school's academic performance suggests a parent may want to look deeper into the school's instructional strategies, support systems, and grade-level trajectories. Without multi-year trend data or a graduation rate, the full picture of student progress through the high school remains unclear.
