7 public K-12 schools in Uniondale from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, Uniondale has more public-school enrollment than 67% of the 4,487 US cities in this directory. Uniondale's average Resource Investment Index falls in the lower portion of the 4,487-city comparison set. The index is a resource snapshot, not an academic grade: it reflects the federal staffing, counselor, gifted-program, and attendance fields available for local campuses. The most useful next step is to open the individual schools below and identify which component is pulling each score down, because the same city average can hide very different campus-level constraints.
Combined-grade campuses shape the local portfolio
5 of Uniondale's 7 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
The composite and staffing measures point in different directions
Uniondale's average Resource Investment Index sits at the 10th percentile, while its teacher-staffing measure sits at the 89th percentile. The 79-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.

Uniondale High School accounts for 31.6% of all Uniondale public-school enrollment
That dominant concentration means Uniondale-wide averages can mask substantial variation outside the largest entity. Grade level: High. The share measures enrollment concentration only; it does not establish how districts allocate programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.
Uniondale school enrollment varies 4.4× across entities
Uniondale school enrollment ranges from 476 students (lowest) to 2,106 students (highest), a spread of 1,630 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.
The reported share clears the 50% majority mark. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.
Uniondale student-teacher ratio is 11.9:1 — low (typically associated with smaller schools or per-school staffing investment that often correlates with stronger per-student supports)
student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
14% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.

Most racially and ethnically mixed schools in Uniondale
Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.

How many schools are in Uniondale, NY? ▼
Uniondale has 7 public schools with a total enrollment of 6,673 students. 1 are charter schools. Average student-teacher ratio: 11.9:1.
Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio,
counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes:
verify current enrollment, attendance boundaries, and programs with the school district before acting. See the guide to understanding NCES data.
