Old Greenwich School, Old Greenwich CT

Original Research by School Decision on Old Greenwich School

Old Greenwich School is a small, early-childhood elementary serving pre-kindergarten through fifth grade in a walkable coastal village. The school sits in the civic heart of Old Greenwich, steps from the train station, village shops, and library, where families can realistically combine school pickup with daily errands on foot.

The student body is predominantly white and affluent. A very small fraction of students qualify for free or reduced-price lunch, reflecting the economic character of the neighborhood. The enrollment is small, particularly in upper elementary grades. Data on special education and English learner populations was not available.

On Connecticut's state assessments, Old Greenwich School shows strong and consistent proficiency across both elementary grade bands tested. In English language arts, students in grades three through five perform at or above typical statewide results, with fifth grade notably strong. Math proficiency is solid across the elementary band, running somewhat above the midpoint for the region. Science testing, available only for fifth grade, shows high proficiency. Across all tested subjects and grades, the school's overall proficiency index places it in the top quartile among the districts in western Connecticut.

The school participates in Connecticut's Science of Reading requirement, which mandates that all districts use an evidence-based K-3 reading curriculum aligned with research on phonemic awareness, phonics, fluency, vocabulary, and comprehension. This represents a state-driven shift in how the youngest readers are instructed.

One contextual note: the Greenwich School District as a whole faces a meaningful infrastructure moment. A new Central Middle School is under construction to replace an aging building, with opening planned for the 2026-2027 school year. Additionally, the district absorbed a budget reduction and explored changes to school start times district-wide, including potential shifts to elementary schedules. Families considering Old Greenwich should check with the school directly about any elementary start-time changes that may affect their schedules.

The village of Old Greenwich itself is affluent, built-out, and settled. It is a place where housing is expensive and the pace is understated. Rail access to New York City via the Old Greenwich Metro-North station is a steady presence; families here often rely on that connection for work. Schools, shops, parks, and the library sit integrated into the village rather than on separated campuses, making the neighborhood school genuinely central to daily life.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
