The top reported proficiency rate is 51% in Math. The lowest is 48% in English language arts.
Original Research by School Decision on Bradley School
Bradley School serves kindergarten through fifth grade in Derby, a compact former industrial city in the Naugatuck Valley about eight miles west of New Haven. The school enrollment is small, spanning just over a hundred students per grade, with a student body that is racially and ethnically mixed: roughly a third Hispanic, a third white, and a fifth Black, with smaller shares of Asian and Native Hawaiian Pacific Islander students. About half the students qualify for free or reduced-price lunch, marking a school where economic need is substantial.
Academic performance shows a mixed picture across the elementary grades. In third grade math, proficiency runs around two-thirds, a solid showing. Fourth grade math results are suppressed from public reporting, so that comparison is not available. Fifth grade math drops notably, with about a third of students meeting proficiency. In English language arts, third grade performance is also suppressed, fourth grade sits at roughly half proficient, and fifth grade holds near that same mark. Science testing occurs only in fifth grade, where proficiency data are suppressed, though the average scale score is available. Overall across all grades and subjects, school-wide proficiency hovers just under two-thirds in both math and language arts, and about three-fifths in science. These figures place Bradley above the midpoint of performance among the seventeen districts in the Naugatuck Valley Planning Region.
The trend data available—covering only the current school year—do not permit a read on whether these results are rising, falling, or stable. A parent may want to look into this further with the school: longer historical trends would show whether performance is improving, whether the sharp drop in fifth grade math is part of a pattern, and whether any instructional changes are underway.
Derby itself is in the early stages of a downtown revival after decades of economic decline. The city's former industrial base of factories and foundries has long departed, leaving legacy riverfront sites now targeted for mixed-use redevelopment. New housing including market-rate and affordable apartments is being built within walking distance of the commuter rail station and Main Street downtown, though redevelopment is still in early phases. Griffin Hospital is the largest anchor employer; retail including Home Depot and Big Y are also significant. The area offers outdoor recreation through Osbornedale State Park and the Derby Greenway along the Housatonic River, and commuter rail service runs from the Derby-Shelton station on the Metro-North Waterbury Branch.
Housing costs in the zip code are moderate by state standards and have risen modestly over the past year. The affordability picture reflects a median home value somewhat below the state benchmark and a typical mortgage payment well below statewide norms, though rent costs run higher relative to typical household income in the area.
A significant consideration for Derby residents: property taxes saw a sharp rise starting in the 2024-2025 school year under a new city administration, after a sustained period of flat taxes. The mill rate increase raised typical homeowner bills substantially. A state-mandated property revaluation for 2026-2027 reset assessed values, with about half of residential owners facing increases of sizable percentages; the city phased in those new assessments to soften the immediate impact. These tax swings directly shape what families will pay going forward and warrant careful attention when weighing a move to the area.
The school district itself remains standalone after a multi-year attempt at regionalization with neighboring Ansonia ended in 2022 without a merger. The district adopted a new phenomena-driven science curriculum at the middle school level in 2023, though that change does not directly affect Bradley's elementary grades.
