Original Research by School Decision on Katonah Elementary School
Katonah Elementary School serves kindergarten through fifth grade in a small residential hamlet in northern Westchester County, with a student body of about four hundred students drawn from an affluent, predominantly white community. The school sits on its own campus on Huntville Road in Katonah proper, part of the Katonah-Lewisboro Union Free School District, which spans five schools across multiple towns; secondary schools are located in Cross River, several miles away.
The school's academic profile is strong. In the most recent state testing, across mathematics and English language arts in grades three through five, proficiency rates range from the high seventies to mid-eighties. In math, about four-fifths of third and fourth graders met the proficiency standard, rising slightly to about eighty-five percent in fifth grade. In English language arts, fourth grade dips to about seventy-nine percent proficiency, while third and fifth grades sit in the high eighties. Science proficiency in fifth grade, the only grade tested, stands at about seventy-five percent. Participation rates on state assessments are consistently in the high eighties to low nineties, indicating strong test-taking engagement. When proficiency rates across tested subjects and grades are averaged, the school lands in the top quartile relative to districts across Westchester County.
The school is a regular public school without charter or magnet status. It does not carry a Title I designation, reflecting the community's economic profile. Free or reduced-price lunch eligibility affects a very small share of students, consistent with Katonah's high-income, built-out residential character. The enrollment is relatively stable and reflects the hamlet's demographics: the great majority of students are white, with meaningful representation of students identifying as multiracial and smaller shares identifying as Hispanic, Asian, and Black.
Katonah itself is a walkable, arts-inflected Victorian hamlet with strong civic anchors in its downtown. The community was rebuilt intentionally in the late 1890s as a planned village and has maintained its character through a deliberate resistance to chain stores and commercial sprawl. A Metro-North station on the Harlem Line puts Grand Central within commuting distance. The Katonah Village Library, local shops, restaurants, and cultural institutions like the Katonah Museum of Art and Caramoor Center for Music and the Arts form the civic core. Parks including Katonah Memorial Park with a pool and fields serve residents.
The housing market is high-priced and built-out. Median home values in the zip code are in the range of just over one million, with limited new construction; properties that come to market tend to be older, well-established homes that sell briskly. The broader Westchester County market shows modest inventory and, recently, a shift in demand dynamics. Rents in the area are comparably steep. A family considering the school should factor that the cost of entry into the Katonah hamlet community, and thus the Katonah Elementary attendance zone, reflects a premium housing market with few affordable options.
The district has undertaken a significant facilities upgrade. A capital bond approved by voters in October 2022 funded improvements across all five schools with work phased through late 2025, including a geothermal heating and cooling system and new maker spaces at Katonah Elementary. This multi-year project modestly raised school taxes, spread over the repayment term. In May 2025, voters narrowly rejected a separate bond that would have converted the long-closed former Lewisboro Elementary School into a universal pre-K center, leaving the district without a dedicated pre-K facility in the near term. The 2025-26 school budget maintains the New York State tax-cap compliance that has characterized recent years, a factor relevant to families weighing long-term tax trajectories.
Katonah Elementary is a small, academically proficient elementary school in an affluent, walk-friendly community with stable performance on state tests and access to strong local civic amenities. The school fits a family seeking a neighborhood-scale school in a high-cost, built-out residential market with limited population churn and strong housing demand.
