Summary

Mile Creek School is a K–5 elementary school in Old Lyme, Connecticut, serving 334 students as part of Regional School District 18. The school is a strong academic performer, ranked 50th out of 491 Connecticut elementary schools for the 2025–2026 school year, placing it in the 90th percentile with a 5-star rating. Test scores are well above state averages across nearly every grade and subject—5th grade ELA proficiency is 87.8% compared to 53.5% statewide, and 4th grade math proficiency is 83.3% versus 52.1% statewide.

Mile Creek stands out for its exceptionally low chronic absenteeism rate of 3.7% in 2025–2026, compared to 10.1% for the district and 16.4% statewide. The school also serves a relatively economically advantaged population, with only about 9.6% of students qualifying for free or reduced-price lunch—the lowest rate among nearby elementary schools. By comparison, The Friendship School has 66.7% of students qualifying, and Daisy Ingraham School has 37.3%. Mile Creek’s student–teacher ratio of 12.9 is higher than many neighboring schools, yet the school still posts top-tier results. Its sister school in Regional School District 18, Lyme Consolidated School, has a higher poverty rate (23%) and slightly lower test scores but remains competitive in math.

While Mile Creek remains an elite school, it has slipped modestly from its peak. The school ranked 22nd in the state in 2016–2017 but dipped to as low as 79th in 2023–2024 before bouncing back to 50th. One area to watch is 3rd-grade math, where proficiency (69.8%) trails the district average (73.1%). Male students’ statewide ranking also dropped from the 94th percentile to the 60th percentile in one year, though this may reflect normal year-to-year variation in a small cohort. Nearby Niantic Center School, ranked 16th in the state, outpaces Mile Creek in math, with 84.2% of 3rd graders and 91.9% of 4th graders proficient. For parents, Mile Creek remains an excellent choice with strong fundamentals, a supportive community, and a track record of academic success.
