Island Trees Union Free School District, NY

Original Research by School Decision on Island Trees Union Free School District

Island Trees Union Free School District serves a community across parts of Nassau County including Bethpage, Levittown, and Seaford. The district enrolls a mid-sized student population from pre-kindergarten through twelfth grade, with an enrollment that is diverse by race and ethnicity, including substantial Asian and Hispanic populations as well as a majority-white cohort.

The district's state test results show proficiency that runs below the midpoint among Nassau County's districts when measured across all tested subjects and grade levels. The picture varies by subject and grade. In math, third and fourth graders show stronger proficiency, while by sixth grade and especially eighth grade the proficiency rates decline notably. English language arts follows a similar pattern, with solid performance in grade four but dips in sixth and eighth grades. Science proficiency in fifth grade sits in the mid-range, and eighth-grade science shows the lowest performance across the tested subjects. The data reflects a common district pattern: early elementary strength that narrows as students progress, with the largest drops occurring at transition points to middle and high school grades.

Chronic absenteeism in the district sits slightly above the county median, a factor worth monitoring as it can correlate with academic outcomes. The district's per-pupil spending falls in the middle range, toward the lower half, compared to other Nassau County districts.

The community's housing market reflects typical Long Island suburban characteristics. Home values have been rising steadily, though some inventory volatility exists. Rental costs remain substantial, and the affordability calculation shows that the typical renter household spends a significant share of income on housing. The mortgage rate environment has been stable in recent months at moderate-to-high levels by historical standards.

Two factors affecting the district's financial profile deserve note. In June 2021, voters approved a capital improvement bond for facility upgrades including a new gymnasium and replacement of the aging synthetic athletic field. Those improvements have multi-year repayment implications for property taxes. More broadly, the district's operating budget and property-tax levy have climbed each year, with increases in recent budgets and a planned increase for the 2025-2026 school year. These trends directly affect what homeowners pay annually in tax bills.

The district operates four schools: two elementary buildings, a middle school, and a high school. Data on advanced coursework, career pathways, or detailed program offerings was not available, so a parent interested in what academic choices exist at the high school level or in specialized programming would want to review the district's course catalogs directly. Graduation rate data for the high school was not provided, leaving that metric for individual verification with the district.
