Island Trees High School, Levittown NY

Original Research by School Decision on Island Trees High School

Island Trees High School is a public high school in Levittown, Nassau County, serving students in grades nine through twelve. The school enrolls roughly seven hundred students across four grades, with the largest cohort in the senior class.

The student body is racially and ethnically mixed. About half the enrollment identifies as white, with substantial representation from Hispanic, Asian, and smaller populations of Black and multiracial students. A meaningful share of families qualify for free or reduced-price lunch, reflecting a cross-section of working and middle-income households in the district. Specific counts of English learners and students with disabilities were not available in the data reviewed.

State assessment results and proficiency data for this school were not provided, so an evaluation of academic performance against state benchmarks cannot be made here. A parent wanting a clear picture of test results, course-level performance, and how the school ranks among Nassau County high schools may want to look into those specifics directly with the school or through the New York State Education Department.

The school does not report a graduation rate in the available data. This is a notable gap; a family considering enrollment would benefit from asking the high school directly about four-year graduation outcomes and what supports exist for students on differing post-secondary pathways.

Levittown itself is a largely built-out, car-oriented suburb developed as the first mass-produced suburb in America, planned with homes, schools, parks, and pools woven through tree-lined residential blocks. Single-family Cape Cod-style homes, many expanded or remodeled over decades, dominate. Ownership rates remain very high. Commercial life clusters along the Hempstead Turnpike corridor rather than forming a traditional walkable downtown. The community is stable in population; recent growth comes through infill and redevelopment of vacant properties rather than large new subdivisions.

Housing in the Levittown zip code sits at a mid-range price point within Nassau County, with the median home value appreciating modestly year over year. Monthly rents in the area run substantially higher than typical mortgages, making home purchase more affordable relative to renting on a payment-per-month basis. Commuting to New York City by car takes a moderate span of time, and the LIRR serves nearby stations. The Levittown Public Library and a network of neighborhood parks, pools, and playfields anchor community life.

Island Trees Union Free School District, the parent of this high school, has approved capital bond funding for facility improvements including a new gymnasium and synthetic turf field replacement, multi-year projects that carry lasting tax implications. District budgets have climbed in recent years, with annual tax-levy increases hovering near or just above typical state allowances. A parent entering this district should be aware that property tax expenses in the area trend upward as bond repayment and operational costs rise.

The federal source publishes a banded range instead of an exact rate when the graduating cohort is small enough that an exact number could risk identifying individual students.

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.
