Longwood High School, Middle Island NY

Original Research by School Decision on Longwood High School

Longwood High School is a suburban four-year public high school on Long Island serving grades nine through twelve in Middle Island, a residential hamlet in the Town of Brookhaven. The school draws roughly equal cohorts of students across its four grade levels, with an enrollment of about three thousand.

The student body reflects Long Island's diversity. White and Hispanic students each represent substantial portions of enrollment. Black students make up a meaningful share, as do Asian students and those identifying as two or more races. Fewer than one in twenty students are American Indian, Alaska Native, or Native Hawaiian Pacific Islander. Roughly two in five students qualify for free or reduced-price lunch, indicating a working-to-middle-class base across the school community.

State assessment results were not available in the data provided. Graduation rate and chronic absenteeism data were also absent, which often points to incomplete reporting rather than gaps in performance; a parent would benefit from asking the school directly about these metrics and checking the district's own reporting on these outcomes. Comparisons to other Suffolk County districts on proficiency and graduation were not possible because the school's figures were missing.

The district context frames important developments. In 2024, voters approved a major capital improvement bond funding security upgrades, infrastructure repairs, bathroom renovations, and expanded career and technical education programs. Ground has since broken on a new state-of-the-art Career and Technical Education center at Longwood High School. That investment will house several credential-bearing pathways including automotive technology, cosmetology, barbering, culinary arts, engineering and advanced manufacturing, medical assisting, and media production. For families interested in hands-on, work-aligned learning leading directly to employment or post-secondary certification, this expansion materially enlarges the school's offerings.

The property market in the 11953 zip code shows moderate upward momentum. Home values have risen modestly over the past year. The median listing price stands in the mid-range for Suffolk County; a household earning the county median income would face a price-to-income ratio that marks the area as moderately expensive but not unaffordable relative to the broader county and state. The rental market is tighter, with rent consuming half of household income at the county median. Days on market have shortened, and supply is rising, suggesting buyers have somewhat more leverage than in recent years, though the overall market leans toward sellers.

The district itself has benefited from New York State's full funding of the Foundation Aid formula, which allowed Longwood to hold a recent tax levy increase to one of the smallest increases in more than a decade. That fiscal relief is pertinent to families weighing the cost of living in this area.

Middle Island itself is a quiet, car-dependent residential community of moderate density situated between other Long Island hamlets. The immediate area offers limited walkable retail or downtown character; commercial life is dispersed across the broader region. The school serves a community built around family housing and commuting, without major employers or civic anchors localized in Middle Island itself.

Longwood High School fits families seeking a traditional public high school of substantial size, with a diverse peer group, in a stable suburban setting where vocational and career pathways are a growing asset. The new CTE center speaks to a district investing in multiple academic and work-entry routes. A parent may want to look into the school directly for current test data, college-acceptance rates, and course breadth outside the career-technical track, as well as the flavor of student life and support services. These details will sharpen the picture beyond what was 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.
