Original Research by School Decision on Heim Elementary School
Heim Elementary serves kindergarten through fourth grade in Williamsville, a walkable, historic village about eight miles northeast of downtown Buffalo. The school is part of the Williamsville Central School District, which spans Williamsville, Amherst, Cheektowaga, and Clarence with about eight schools across the elementary grades.
The school's enrollment sits around a mid-sized figure for its grade band, with a student body that is predominantly white and relatively affluent. About a fifth of students qualify for free or reduced-price lunch, which is modest compared to many districts. Demographic data on special education enrollment and English learners was not available.
In state testing for 2024-25, Heim's math proficiency runs broadly solid. Third graders showed strong results, and fourth graders performed somewhat higher. In English language arts, proficiency is lower. Third graders scored moderately, while fourth graders fell to just under three-fifths meeting the state standard. Science data, from 2021-22, showed strong performance at fourth grade, though more recent science results were not reported. Overall, across tested grades and subjects, the school's proficiency index places it in the top quartile among districts in Erie County.
The state testing data shows higher participation rates in fourth grade than third, which may reflect different test conditions or absences. Parents may want to ask the school directly about efforts to improve ELA proficiency, particularly at the fourth-grade level.
Williamsville itself is a mixed-use village with a strong commercial and civic center on Main Street, lined with locally owned businesses, restaurants, a brewery, patios, and restored mill buildings dating to the 1800s. The village is comparatively walkable for a Buffalo suburb, with a Walk Score rating that reflects an active main corridor alongside quieter residential streets. Glen Park and Island Park anchor the village's six parks, and the Williamsville Branch Library sits centrally, near both town and village halls. A farmers market, creekside paths, and seasonal festivals like Old Home Days give the place a neighborhood feel oriented toward families.
Housing in the Williamsville zip code reflects the region's character. The median home value sits solidly in the mid to upper hundreds of thousands, with rents around the mid-two-thousands monthly. The local housing market has seen a modest increase in listings and supply recently, though median listing prices have edged down slightly year-over-year. Affordability is moderate; a buyer at median price would face a monthly mortgage roughly in line with local rents, and housing costs consume about a quarter to a third of regional household income.
The Williamsville district is currently in the midst of a multiphase air-conditioning capital project affecting elementary schools, including Heim, with installation work scheduled through 2027-2028. This project was approved by voters and structured to avoid raising the tax rate. Additionally, townwide property reassessments in Amherst and Clarence, moving to full market value, have reshaped school tax bills for individual homeowners, with some seeing increases and others decreases depending on their new assessment.
Heim sits on a suburban campus rather than in the village center, like most of the district's schools. The school draws families seeking a neighborhood-oriented suburban elementary with solid proficiency in math and average performance overall among its county peer group. A parent considering enrollment should note the lower ELA proficiency at fourth grade and may want to inquire directly about reading support and intervention practices at the school.
