Lindenhurst Middle School, Lindenhurst NY

Original Research by School Decision on Lindenhurst Middle School

Lindenhurst Middle School serves grades six through eight in a suburban Long Island community and educates a diverse student body, with roughly half of students qualifying for free or reduced-price lunch and a racial and ethnic composition that is predominantly white and Hispanic, with smaller Asian, Black, and multiracial populations.

The school's state testing performance reveals mixed results. In sixth-grade English Language Arts, about half of students scored at proficiency level or above. Sixth-grade math shows roughly the same proportion meeting the state standard. By seventh grade, performance declines noticeably in English Language Arts, where fewer than one-third of students achieved proficiency, though math holds steady at a similar level to sixth grade. Eighth-grade English Language Arts rebounds to about half of students proficient, but eighth-grade science proficiency is substantially lower, with one-fifth of students meeting the standard. Test participation rates, however, signal a potential data concern: participation in the tested grades ranges from roughly one-fifth to one-quarter of students, well below the typical participation expected on state mandated assessments. This unusually low participation rate may reflect a combination of factors—such as students opting out, being absent on test days, or other operational circumstances—and a parent may want to look into this further with the school to understand what is driving these numbers.

Comparing the school to other districts in Suffolk County, Lindenhurst Middle School's overall proficiency index falls in the bottom quartile, meaning its tested performance is lower than the median and the vast majority of its county neighbors. The school's strengths in eighth-grade ELA are modest relative to county performance as a whole.

The enrollment is typical for a middle school, with three grades housed in a single building and fairly balanced cohort sizes across sixth, seventh, and eighth grade. The community context is a suburban, car-dependent residential village where most families own homes and commute outside the immediate area for work. Housing values in the zip code have held relatively steady with moderate year-over-year appreciation. The Lindenhurst Union Free School District, which operates this school, recently brought a substantial capital bond to voters—its first in over a decade—to fund districtwide improvements including classroom air conditioning, roof and window work, electrical upgrades, bathroom renovations, and athletic field projects. The district also operates a notable Spanish Dual Language two-way immersion program at one of its elementary schools, serving families who want their children to become bilingual and biliterate.

Lindenhurst Middle School is a regular public middle school without charter or magnet designation, serving its assigned attendance area. Data on special education enrollment rates, English learner populations, chronic absenteeism, and staffing levels were not available. The school's academic environment, program breadth, and student support systems would benefit from direct conversation with school leadership.

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.
