Summary:
ZIP code 06811 in Danbury, Connecticut is home to seven public elementary schools serving about 2,655 students in grades K–5, all within the Danbury School District, which ranks 134 out of 153 in Connecticut. The standout is Great Plain School, ranking in the 66th percentile statewide (165 of 491) and the only school in the ZIP code to consistently exceed both district and state proficiency averages in ELA, math, and science. Great Plain also has the lowest free/reduced lunch rate (42.8%) and the lowest student–teacher ratio (12.9). Pembroke School shows the most dramatic improvement, climbing from the 16th percentile in 2023–24 to the 33rd percentile in 2025–26, with 3rd grade math proficiency (53.7%) now above the state average. The K–3 primary schools, King Street Primary School and Mill Ridge Primary School, also beat district averages in 3rd grade ELA and math.
Most other schools cluster in the bottom 20–30 percent statewide: Stadley Rough School (19th percentile), Hayestown Avenue School (27th), and King Street Intermediate School (30th) all trail far behind Great Plain despite sharing the same district and similar funding. Spending does not explain the gap—Great Plain spends near the average ($12,400) and outperforms, while Hayestown spends the least ($11,254). Poverty is a factor, but not the whole story: King Street Intermediate has a moderate poverty rate and still outperforms Hayestown in 4th grade, showing that school-level factors matter.
A concerning pattern is the sharp decline in math proficiency from 4th to 5th grade: Hayestown drops from 49.3% to 25.7%, King Street Intermediate from 47.8% to 25.1%, and even Great Plain falls from 76.0% to 58.3%. 5th grade science is also weak except at Great Plain. On the positive side, chronic absenteeism is a real strength—every school is below both the district (14.7%) and state (16.4%) averages, ranging from 6.1% at Mill Ridge to 12.7% at Pembroke. For parents, Great Plain is the clear academic leader, Pembroke is on the rise, and the primary schools provide a solid early foundation—but upper-elementary math and science need attention.
