Original Research by School Decision on Hamilton Avenue School
Hamilton Avenue School serves the earliest grades in Greenwich, covering preschool through fifth grade in a regular public school setting. The student body of about two hundred students reflects the demographic diversity of central Greenwich: more than half identify as Hispanic, roughly a third are white, with smaller numbers of Asian, Black, and multiracial students. A substantial share of students qualify for free or reduced-price lunch, suggesting economic diversity within a town known primarily for affluence.
On state testing, the school's performance is mixed. In math, Hamilton Avenue shows strength in the upper grades, with proficiency rates climbing from roughly mid-range in third grade to near or above two-thirds in fourth and especially fifth grade. English language arts results follow a similar pattern, with fourth and fifth graders reaching proficiency at similar rates; third-grade data was suppressed. Science proficiency at fifth grade was also suppressed. Across the subjects and grades where results were available, the school's overall proficiency index falls below the midpoint when compared to other districts in Western Connecticut Planning Region, a signal that the school's academic performance trails the regional average. A parent or resident should look into what this means in context of the district's curriculum changes and resource allocation.
The context matters. Greenwich recently passed the state's Right to Read law, which requires all districts to adopt a Science of Reading-aligned K-3 curriculum by 2025. Hamilton Avenue, as one of the district's early-grade schools, is in the middle of that transition. Additionally, the district faced a significant budget cut in 2025 that led the Board of Education to consider changes in start times across schools. Understanding how the school and district are navigating curriculum changes and budget constraints will help frame what the test numbers represent.
Greenwich itself is an affluent, predominantly residential town on Long Island Sound with a strong downtown walkable core along Greenwich Avenue, distinct neighborhoods ranging from village centers to rural estates, and major employment in finance and hedge funds. Four Metro-North stations provide commuter rail access to New York City. Housing values are very high; rents are correspondingly steep. The town has seen stable population since around mid-century, with recent development focused on multifamily housing and affordable-unit requirements. Civic life centers on shoreline parks, a strong library system, and schools assigned by residence across neighborhoods.
Hamilton Avenue's location on Hamilton Avenue places it in or near central Greenwich, within walking distance of the downtown core. For a family considering the school, the appeal or fit depends on whether you want an early-grade elementary in a diverse, economically mixed cohort within an affluent town, where testing results are still developing and the school is in the midst of district-wide curriculum and scheduling changes. The school is not an outlier in any direction—it is a regular neighborhood school serving a real cross-section of Greenwich families—but a parent should understand its current academic standing relative to the district and region, and track how the Right to Read implementation and any operational shifts affect teaching and learning over the next year or two.
