Longwood Middle School, Middle Island NY

Original Research by School Decision on Longwood Middle School

Longwood Middle School is a public middle school serving grades five and six in Middle Island, a moderate-density residential hamlet on Long Island in Suffolk County. The school enrolls students across a range of backgrounds: roughly two-fifths are White, about a third Hispanic, and roughly one-fifth Black, with a substantial share of students qualifying for free or reduced-price lunch. The school is part of Longwood Central School District, which recently approved a major capital improvement bond that funded district-wide infrastructure upgrades and is now constructing a new Career and Technical Education center at the high school level.

State testing results from the most recent school year paint a picture of academic performance below the county median. In fifth-grade mathematics, proficiency sits in the lower-middle range. Fifth-grade English language arts results are higher than math but still well below typical district benchmarks. Sixth-grade results show similar patterns: math proficiency holds at a similar level to fifth grade, while ELA proficiency dips noticeably. Fifth-grade science proficiency is modest. Overall across tested subjects and grades, the school's proficiency index places it in the bottom quartile relative to the other districts in Suffolk County, a positioning that reflects widespread struggle with mastery of grade-level standards in math and English language arts.

Test participation rates are concerning. In grade six, a material share of enrolled students did not participate in the assessments; rates below two-thirds raise questions about absences, opt-outs, or other barriers to full-class testing. Fifth-grade participation is somewhat better but still shy of universal. A parent may want to ask the school directly about the reasons for lower participation and what supports exist for students who miss testing days.

The school's staffing and student support infrastructure are not detailed in available public data. No information was reported on the prevalence of students with individualized education plans (IEPs) or English learners, so a parent would need to inquire directly about special education and English learner services and how students are placed and supported in those programs.

Middle Island itself is a quiet suburban residential community with moderate density. Median home values in the zip code are in the upper range for suburban Long Island. The district's recent decisions around facility investment and tax relief suggest a community engaged in long-term planning, and the expansion of career and technical pathways at the high school level indicates an effort to broaden options for students beyond traditional academic tracks.

For families considering this school, the core question is whether you are comfortable with below-county-average performance on standardized assessments in the foundational subjects, and whether the school's approach to intervention and support aligns with your child's needs. Families seeking a school with strong results on state tests may want to explore other options in the county. Families drawn to a suburban setting who have time and resources to provide home support may find the school workable but should seek clarity from administrators about what diagnostic and remedial services are available.

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.
