Locust Valley High School, Locust Valley NY

Original Research by School Decision on Locust Valley High School

Locust Valley High School serves the secondary grades in a small, established Long Island district. The school enrolls a modest student body drawn from a affluent residential community where home values are high and the housing market shows steady momentum.

The student composition leans predominantly white, with a meaningful Hispanic enrollment and smaller Asian representation. About a quarter of students qualify for free or reduced-price lunch, a rate that reflects some economic diversity within an otherwise wealthy zip code. The freshman class is noticeably larger than the cohorts that follow, which may reflect enrollment patterns in the feeder elementary grades or demographic shifts in the district over time.

The school's academic performance data are unavailable, and state testing results were not provided in the records searched, so a reader cannot assess how students perform on New York's standardized assessments or how the school compares on those measures to peers in Nassau County. Likewise, a four-year graduation rate was not available. Without these metrics, the clearest picture comes from the district and housing context rather than direct school performance reporting.

The district itself faces near-term fiscal pressure. Voters rejected the proposed 2026-2027 budget in May 2026, marking the first defeat after the prior year's approval. A revised budget was presented for a June revote, but the situation created real uncertainty about whether extracurricular programs and athletics could be sustained if a contingency budget had to be adopted. For families weighing a move to Locust Valley, this signals an active community conversation about resource allocation and may warrant a direct conversation with the district about the current budget timeline and any resulting cuts or delays to programs.

On a more concrete level, the district approved a transportation policy expansion effective 2026-2027 that extends busing eligibility to all students regardless of distance, eliminating prior thresholds and increasing the maximum eligible distance. This change removes a barrier that previously would have required families living beyond certain distances to provide their own transportation, and it required no additional tax levy to implement.

The district has also shifted its literacy curriculum across elementary grades, adopting a research-based framework beginning in fall 2024 after a pilot year. That change cascades into the high school pipeline, shaping how reading and writing have been taught to incoming ninth graders.

Housing in the 11560 zip code remains affluent and stable. Median home values are well above state and national benchmarks, though they track the broader Long Island market dynamics. The rental market is tight relative to income. Properties are moving briskly, and new inventory remains moderate. A parent considering the area should factor in that housing costs are substantial and that mortgage affordability sits at a meaningful multiple of household income.

The school sits in a district that includes multiple grade bands but is itself a high school only, serving grades nine through twelve. Without direct academic outcome data attached to this school, a prospective family would benefit from requesting recent standardized test results, graduation data, and program offerings directly from the school or district office. The local housing market and transportation policy are clearer indicators of fit than the academic reporting available here.

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.
