Increase Miller Elementary School, Goldens Bridge NY

Original Research by School Decision on Increase Miller Elementary School

Increase Miller Elementary School serves kindergarten through fifth grade in Goldens Bridge, a small hamlet in Lewisboro within Westchester County. The school is part of the Katonah-Lewisboro Union Free School District, which operates five schools across the area.

The school's recent state test results show solid proficiency across the grades and subjects tested. In mathematics, students in grades three through five achieved proficiency rates ranging from the low eighties to low nineties. English language arts results were similarly strong, with proficiency rates in the mid-to-high eighties and into the nineties. Science proficiency in grade five, the only grade tested in science, was somewhat lower at in the low seventies, suggesting that may be an area to explore further if you have science-focused interests. Overall, the school's proficiency index places it in the top quartile among Westchester County districts, reflecting consistently strong academic performance.

The school enrolls a small student population, predominantly white, with smaller shares of Hispanic, multiracial, and Asian students. Only a small portion of students qualify for free or reduced-price lunch, indicating an overall affluent student body. Data on the school's special education and English learner populations was not available.

Goldens Bridge sits along the Metro-North Harlem Line, with commuter service to Grand Central. The hamlet's housing market is expensive, reflecting broader Westchester patterns. The most recent significant housing addition has been Lewisboro Commons, an affordable-housing development with apartments completed in 2022 near the station. Rental inventory in Goldens Bridge remains limited.

The district has been active in capital improvements. Voters approved a major bond in October 2022 to upgrade facilities across all five schools, with construction phased through fall 2025 and bond payments spread over a period that modestly raised school taxes. However, in May 2025, voters narrowly rejected a bond proposal to convert a former school building into a universal pre-K center, leaving the district without a universal pre-K facility in the near term. The district's 2025-26 budget stayed within New York's tax-cap limit, continuing a pattern of predictable, capped tax increases.

Increase Miller is a regular public elementary school with no specialized program designation. It draws families from an affluent suburban community with straightforward college-preparatory expectations. The school's strong academic results and small size make it a typical choice for families whose children are in the elementary grades and who are looking for consistent proficiency and a peer environment shaped by the hamlet's demographic composition.

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.
