Bayville Primary, Bayville NY - Test Scores & Data

Original Research by School Decision on Bayville Primary

Bayville Primary serves children in prekindergarten through second grade in a small, affluent waterfront village on Long Island's North Shore. The school sits on a hill on Godfrey Avenue near the village center, within walking distance of the civic core anchored by the library and waterfront parks.

The enrollment is small for its grade band, drawn almost entirely from the immediate community. A large majority of students are white; the student body also includes a modest share of Hispanic students and smaller numbers of Asian and Black students. About one in six students qualify for free or reduced-price lunch, substantially below the county average, reflecting the village's economic profile.

State testing data from 2017-18 shows the school's academic position. In mathematics, proficiency rates across grades three through five run very high: students in grades three and four achieved proficiency at rates well above the threshold, while grade five showed a measurable dip to a still-solid level. English language arts performance is notably different. Reading proficiency in grades three and four sits in the low eighties, but by grade five it falls into the upper fifties, a material drop that a parent may want to look into further with the school. Science results show strong performance, with every fourth-grade student tested reaching proficiency. Overall, the school's proficiency index places it in the top quartile among districts across Nassau County, reflecting the dominance of very strong math results and the drag of weaker literacy performance at the upper grades served.

The data does not include current attendance, discipline, staffing, or recent trend information, so a parent should ask the school directly about how instruction has evolved since 2017-18 and how the district's new core literacy curriculum, adopted in fall 2024, is shaping early reading instruction.

Bayville is a quiet, predominantly residential village where most economic activity is small-scale: a modest commercial strip along the beach, seasonal recreation businesses, and professional workers who commute to Manhattan via rail or work from home. The housing market is affluent. Waterfront and renovated homes command high prices; the median home value in the zip code is substantial, and listing prices reflect the village's position on Long Island Sound. The market shows modest seasonal fluctuation with buyer interest rising in spring and summer.

The wider district context matters here. Locust Valley Central School District covers three villages and serves students through high school, which sits in neighboring Lattingtown. The district recently faced a budget referendum defeat in May 2026, a first in recent years, forcing a revote and raising questions about fiscal pressures. Parents should understand this backdrop. On a positive note, voters approved a transportation policy change effective 2026-27 that expands busing to all elementary students regardless of distance, a change that could affect where a family lives relative to the school.

This is a school for early elementary students in an economically stable, tight-knit waterfront community. The academic profile reflects strength in foundational mathematics but uneven literacy performance that merits direct conversation with educators before enrollment.

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.
