Summary:
Darien School District serves roughly 4,649 students in 7 schools—1 high school, 1 middle school, and 5 elementary schools—in the affluent coastal community of Darien, Connecticut. The district ranks #6 out of 153 districts statewide (96th percentile), holds a 5-star rating, and every one of its schools is rated 5 stars. Enrollment ranges from 342 students at Royle Elementary School to 1,382 at Darien High School.
Darien High School is the district's top secondary school, ranked #5 of 133 high schools with a 98.3% graduation rate and SAT/NGSS proficiency roughly 40–45 percentage points above state averages. Among elementary schools, Tokeneke Elementary School (#6 of 491) and Royle Elementary School (#9 of 491) lead the district with average proficiency near 87%, including standout 3rd–5th grade ELA scores. Ox Ridge Elementary School, Hindley Elementary School, and Holmes Elementary School are also strong, with proficiency near 80% and state rankings between #30 and #45.
Middlesex Middle School ranks #6 of 258 middle schools academically, but its 8.4% chronic absenteeism rate is nearly double the district average of 4.4% and the clearest area for improvement. Even in this elite district, grade-level dips appear: Hindley's 4th grade ELA proficiency was 65.3% and Holmes' 5th grade math was 68.4% in 2025-2026. Scores dipped in many subjects year-over-year, yet Tokeneke and Royle climbed dramatically in state rankings, highlighting how small cohorts can drive volatility. Per-student spending ranges from $18,876 at Holmes to $21,860 at Middlesex, with student-teacher ratios from 9.9:1 to 13.7:1—suggesting demographics and grade-level dynamics matter more than funding alone in this resource-rich district.
