Schools in Zip Code 06422

Zip code 06422 serves the Durham, Connecticut area through three public schools in Regional School District 13: Coginchaug Regional High School (grades 9–12, 356 students), Frank Ward Strong School (grades 5–8, 319 students), and Frederick Brewster School (grades PK–1, 214 students), all of which benefit from high spending and low student-teacher ratios.

Coginchaug Regional High School is the clear academic standout, ranking 23rd out of 133 high schools in Connecticut (83rd percentile) with a 4-star rating. It consistently ranks in the top quartile, and its 92.5% graduation rate and SAT/NGSS proficiency rates far exceed state averages. In contrast, Frank Ward Strong School shows more mixed results: it ranks in the 67th percentile among middle schools, with strong 7th grade math (56.7% proficient vs. 44.1% statewide) but weak 5th grade math (35.4% vs. 45.8% statewide). Its 8th grade ELA proficiency also dropped sharply from 70.8% to 54.0% year over year. Frederick Brewster School has no test rankings due to its PK–1 grade span, but it stands out with a 5.1% chronic absenteeism rate.

All three schools share a consistent economic profile, with free/reduced lunch rates tightly clustered between 15.73% and 17.76%, and every school keeps chronic absenteeism below 9%—far better than the 16.4% state average. Per-student spending exceeds $21,000 at each school, and student-teacher ratios range from 8.8:1 to 10.4:1, reflecting strong resource investment across the district. While the district itself ranks at the 50th percentile statewide, the high school's 83rd percentile ranking suggests the district's overall rating is dragged down by the middle school. For parents, this is a well-resourced, economically stable community where the high school is a genuine strength and early-grade attendance is excellent.
