West Side School, Syosset NY - Test Scores & Data

Original Research by School Decision on West Side School

West Side School is a public elementary school in Syosset serving grades two through six in the Cold Spring Harbor Central School District. It sits in an affluent residential suburb on Long Island's North Shore, roughly a half-hour east of Manhattan, in a community where median home values are high, housing values have been appreciating steadily, and the school district itself functions as one of the area's largest employers.

The school's academic performance is strong across the board. In math, proficiency rates range from the high seventies in grade three to the mid-nineties in grade four, with fifth and sixth grades in the low nineties. In English language arts, performance is somewhat more varied: grade three and four show proficiency in the low eighties, while grades five and six move into the upper eighties and low nineties. Science proficiency in grade five reaches the low eighties. When measured against other districts in Nassau County, the school's overall proficiency index places it in the top quartile. Testing participation is consistently high across grades, above ninety percent, suggesting solid engagement with assessments.

The student body is small, around two hundred students, with a composition that is predominantly white, reflecting the broader demographic makeup of the Syosset area. A small share of students qualify for free or reduced-price lunch, consistent with the community's economic profile. Information about students with IEPs or English learners was not available in the data.

West Side feeds into the Cold Spring Harbor district's middle schools as students advance beyond sixth grade. The district has recently launched a new in-district pre-kindergarten program, beginning in fall 2024, offering families an early-education option that did not previously exist within the district. Budget and tax-levy increases have been modest and voter-approved in recent years, offering some clarity on the fiscal trajectory for families weighing property-tax costs.

The school's grades two through six focus sits in the elementary band, so state testing results do not include standardized assessments for second grade, nor do they include high school graduation data or secondary-level outcomes. The data provided does not include information about specific enrichment programs, special education placements, or detailed staffing composition at West Side itself.

Syosset is a family-oriented community with strong school pride. Walkability outside a small downtown core is limited and car-dependent, but the town offers a well-funded public library, an eighty-acre community park with sports and recreation facilities, and LIRR access to Manhattan for commuters. Housing has appreciated modestly in recent years, and the local market shows moderate activity. A major brownfield redevelopment on former industrial land off Robbins Lane remains in planning phases, with proposals ranging from mixed-use residential and retail to warehousing, though plans have shifted over time and the final outcome remains unsettled.

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.
