H B Mattlin Middle School, Plainview NY

Original Research by School Decision on H B Mattlin Middle School

H B Mattlin Middle School serves a school population of roughly five to eight hundred students in grades five through eight, in the Plainview-Old Bethpage Central School District, serving the owner-occupied suburban community of Plainview on Long Island's Nassau County. This is a regular public middle school in a stable, car-oriented residential hamlet with strong housing values, in a school system that has consistently managed its budget below the state property-tax cap.

The school's academic profile shows solid performance in math, with proficiency above the midpoint among Nassau County districts when all tested subjects and grades are averaged together. In math, the school reports particularly strong results in grade six, where the vast majority of tested students reached proficiency. Grades five and seven also show proficiency well above typical benchmarks. Grade eight math proficiency is lower, though state testing participation in that grade is quite small, making the picture less clear. English language arts proficiency is more mixed. Grade six ELA shows strong results; grade five is somewhat lower; and grades seven and eight dip further. Science results are available only for grades five and eight, with grade five showing solid proficiency and grade eight showing lower performance, though again the grade eight participation is limited. The overall proficiency index places this school above the median among Nassau County schools.

One note on the data: participation rates in state testing vary considerably by grade and subject, with lower grades generally showing higher participation and upper grades showing more modest participation. A parent may want to ask the school directly about whether this reflects the school's testing approach or student circumstances, as it can affect how representative the proficiency numbers are.

The student body is predominantly white, with a substantial share of Asian students, a smaller population of Hispanic students, and very few Black or Native American students. A small share of students qualify for free or reduced-price lunch. No recent enrollment data on English learners or students with IEPs was available. The school draws from a community where homeownership is the norm, median housing values are substantial, and the largest private employers nearby include healthcare and technology firms.

The Plainview-Old Bethpage district itself faces ongoing capacity pressures. Voters rejected a bond referendum in January 2025 that would have expanded space at the high school and an elementary school. Since then, the district has shifted to funding facility upgrades through its annual operating budget and capital reserves, including air-conditioning installation in cafeterias, classroom additions at elementary schools, and pool repairs at the high school. This strategy addresses immediate needs without a separate bond but does not fully resolve the underlying crowding. At the same time, the district has held its tax levy below the state cap for more than a decade, a consistent fiscal management signal for families weighing property-tax exposure.

The community itself is car-oriented and lacks a traditional downtown. Retail life organizes around shopping centers and strip malls on Old Country Road and Woodbury Road rather than a walkable core. A significant recent development is Country Pointe Plainview, a mixed-use community on the former Nassau County complex site, mostly comprising market-rate condos for adults 55 and older. The Plainview-Old Bethpage Public Library sits on Old Country Road and functions as a civic anchor, and the community park system offers green space and trails. Bus service is available through Nassau Inter-County Express routes, though owning a car is typical and practical given the spread-out layout.

The state testing data for this school is current to the 2024-25 school year. No graduation rate or chronic absenteeism data applies, as this is a middle school. No data on programs, course access, or staffing levels was available. A family considering this school would benefit from visiting, observing the classrooms and building, and asking directly about the school's approach to mixed proficiency levels across grades and how it supports students moving from elementary to middle and then to the high school.

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.
