6 public K-12 schools in Copiague 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, Copiague has more public-school enrollment than 51% of the 4,487 US cities in this directory. Copiague's 6 listed schools all sit inside one district, creating a compact governance structure with one budget, board, and reporting chain. That makes citywide comparisons cleaner than in places split across several districts, but it does not make the campuses interchangeable: elementary, middle, and high-school staffing needs differ. The ranked list is best read as variation inside one system rather than competition among separate local authorities.
The school portfolio is elementary-weighted
4 of Copiague's 6 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 1 middle and 1 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
The composite and staffing measures point in different directions
Copiague's average Resource Investment Index sits at the 7th percentile, while its teacher-staffing measure sits at the 62nd percentile. The 55-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.

Walter G O'connell Copiague High School accounts for 34.2% of all Copiague public-school enrollment
That dominant concentration means Copiague-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.
Copiague school enrollment varies 3.7× across entities
Copiague school enrollment ranges from 427 students (lowest) to 1,567 students (highest), a spread of 1,140 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.
Copiague operates one school district — a single-district system
Copiague's listed schools share one district boundary, budget authority, and reporting chain. That makes citywide and districtwide governance easier to compare, but it does not make individual campuses uniform: grade configuration, staffing, programs, and student need can still vary materially within the same school district.
Copiague student-teacher ratio is 14.4:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure
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 Variation between sub-units within Copiague is typically wider than the Copiague-aggregate figure suggests.
Most racially and ethnically mixed schools in Copiague
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.

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:
