Lindenhurst Senior High School, Lindenhurst NY

Original Research by School Decision on Lindenhurst Senior High School

Lindenhurst Senior High School serves grades nine through twelve in a suburban setting on Long Island. The school is part of the Lindenhurst Union Free School District, which in May put forward a substantial bond referendum to fund districtwide improvements—the district's first bond proposal in more than eight years. The improvements include air conditioning in classrooms, roof and window replacements, upgraded fire alarms and safety systems, electrical upgrades, ADA accessibility enhancements, bathroom renovations, and parking and sidewalk reconstruction, along with athletic upgrades such as turf fields. For families considering the school, this bond represents a meaningful commitment to infrastructure and a factor in the tax landscape going forward.

The school draws from a diverse enrollment. A substantial share of students qualify for free or reduced-price lunch, indicating economic need across much of the student body. The student population is mixed in racial and ethnic composition, with a majority white enrollment alongside substantial populations of Hispanic students and smaller numbers of students who are Black or Asian. Overall enrollment sits at a mid-size level typical of suburban comprehensive high schools serving a community.

State assessment data for this school was not available for review. The New York State Testing Program results shown in the available data report zero tested students in grades eight across math, English language arts, and science, which reflects the fact that the school serves only grades nine through twelve and does not administer state tests at the high school level. For high school, New York relies on Regents examinations and other pathways rather than the uniform state proficiency assessment used in middle grades. As a result, a direct academic performance picture for this school's high school students from standardized testing cannot be drawn from the data on hand.

When positioned against the seventy-four districts in Suffolk County, the school's proficiency index—a summary of tested performance across subjects and grades—sits in the bottom quartile of the county comparison set. This reflects the absence of tested high school results in the available dataset. A parent seeking a complete academic profile should ask the school directly about Regents exam pass rates, AP participation and performance, or other high school assessment outcomes the district tracks, as these are the metrics that typically show how students in grades nine through twelve are performing.

The community itself is a residential suburb in the Town of Babylon, oriented heavily toward commuting. Most residents drive alone to work, and car ownership averages roughly two per household. The median home value is in the mid-range for the region, and the rental market is moderately priced. The economy in and around Lindenhurst centers on health care, educational services, and retail trade. Northwell Health, a major regional employer, is connected to the area.

The Lindenhurst Union Free School District also operates a Spanish Dual Language two-way immersion program at Albany Avenue Elementary School, created years ago and continuing to enroll a new kindergarten cohort each year. While that program is in the elementary grades and does not directly affect high school enrollment, it signals an ongoing districtwide investment in language learning and shows the kinds of educational pathways available to families within the district as students move through the system.

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.
