Original Research by School Decision on Wampus School

Wampus School is a public elementary school serving grades 3 through 5 in Armonk, part of the Byram Hills Central School District. The school enrolls a small-to-moderate number of students across its three grade levels, with enrollment roughly balanced across the grades.

The student body is predominantly white, with smaller shares of Asian and Hispanic students. Free or reduced-price lunch eligibility is low, reflecting the affluent residential character of Armonk. Data on the proportion of students with individualized education plans and English learners was not available.

Academically, Wampus performs well across tested subjects. In mathematics, proficiency across the school is strong, with grade 4 and 5 students showing particularly high rates of meeting or exceeding state standards, while grade 3 students achieve strong though slightly lower proficiency. English language arts proficiency is solid in grades 4 and 5, with grade 3 showing lower performance in this subject compared to its mathematics results. Grade 5 science proficiency is also strong. Relative to school districts across Westchester County, Wampus ranks in the top quartile for overall proficiency across tested subjects and grades.

The school sits within the Byram Hills district, which spans a rural-fringe area in Westchester County. The district recently made several significant changes relevant to elementary families. In 2024, it adopted the Wonders literacy curriculum alongside Fundations, a structured phonics-based program in grades K-3, reflecting the state's emphasis on science-of-reading instruction. The same year, the district adopted a new K-5 character education curriculum called PurposeFULL People. Additionally, voters approved a capital project at the high school in May 2024 for renovation work scheduled through 2027.

Armonk itself is a small, affluent hamlet in the town of North Castle, dominated by large single-family homes, townhouses, and gated communities. IBM's global headquarters has anchored employment here for decades. The hamlet has little public transit; there is no train station nearby and bus service is limited. Civic life centers on a compact downtown along Main Street and Armonk Square, where shops, cafes, and restaurants cluster, though schools sit on separate campuses rather than in the commercial core. Parks including Wampus Pond Park and John A. Lombardi Park are the main civic anchors. Housing values in the Armonk area are high, and recent residential development has focused on luxury townhomes and condominiums, though the overall pace of new construction remains modest. The Westchester County housing market has shown some recent softening in active listings and pending sales relative to the prior year, though median listing prices have edged upward.

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.
