Clinton Avenue School, Port Jefferson Sta NY

Original Research by School Decision on Clinton Avenue School

Clinton Avenue School serves kindergarten through second grade in Port Jefferson Station, a suburban hamlet on Long Island's North Shore. The school is part of the Brookhaven-Comsewogue Union Free School District and draws students from a diverse, mixed-income community where about forty percent of families qualify for free or reduced-price lunch. The student body is roughly evenly split between white and Hispanic students, with smaller Asian and Black populations and a few students from other backgrounds.

The school's recent state test results, from 2011-12, show students performing above the county median across tested subjects. In mathematics, proficiency rates ranged from about two-thirds to three-quarters, with grade five reaching the strongest performance. English language arts results were similar, ranging from about sixty to seventy-five percent, with fourth grade notably stronger. In science, fourth graders demonstrated proficiency well above typical levels. The school posted exceptionally high proficiency in social studies when tested. These results place Clinton Avenue in the top quartile of Suffolk County school buildings on an overall proficiency index, relative to districts in the county.

The student enrollment is small to moderate for an elementary school of this grade band, with roughly equal classes across the three grades served. The age of the test data means it does not reflect current instruction or population, and no state assessment results are available from more recent years, a gap that reflects shifts in New York's testing timeline and grade-level coverage. Special education and English learner enrollment data were not available in the records provided.

Port Jefferson Station itself is in a period of active change. The commercial landscape along the main retail corridors has long been dominated by aging strip centers and highway-oriented development, but a major mixed-use redevelopment project began demolition in early 2026 at the large Jefferson Plaza site, with plans for hundreds of apartments, ground-floor retail, and a civic plaza. Affordable and supportive housing has already opened nearby, and the state has committed resources to infrastructure planning. The hamlet remains car-dependent, though a paved greenway trail provides a strong off-street walking and cycling route, and the Long Island Rail Road's Port Jefferson terminal at the hamlet's northern edge offers diesel service with connections to county transit.

Housing values in the zip code have appreciated modestly over the past year. Median home values sit in the mid-range for Long Island, and rental costs are moderate relative to local incomes. The area's economy centers on health care, education, and retail employment, with the school district itself a significant institutional anchor alongside nearby regional employers and the Comsewogue Public Library.

For families considering Clinton Avenue School, the key takeaway is a small elementary school in a diverse, working- and middle-class community with historical test proficiency above the county norm. The school serves the youngest grades only, so it functions as part of a K-8 pathway within the district rather than as a standalone entity. The test data available is more than a decade old, so a parent may want to look into more recent school performance information and current program offerings directly with the building or district. The neighborhood itself is stable and suburban, with ongoing redevelopment that may reshape the commercial character of Port Jefferson Station over the next several years.

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.
