How the COLONIA Public-School Landscape Breaks Down
COLONIA, NJ enrolls 3,162 students across 6 public schools reporting to the National Center for Education Statistics. The average student-teacher ratio across the city is 11.8:1, Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.
The highest-ranked campus in COLONIA is Colonia High School, scoring 60/100 (C+) with 1,354 enrolled students at the high level. Families should treat any single ranking as a starting point rather than a verdict — a school serving fewer at-risk students or offering more AP classes will score higher on resource-based composites even if individual teachers or programs elsewhere are stronger. The quality score framework is transparent and rebuilt from raw NCES and Civil Rights Data Collection (CRDC) inputs, so each component can be inspected on the individual school pages linked in the table below.
COLONIA schools sit within multiple district boundaries, which matters for property taxes, redistricting votes, and bond measures. Each district files its own NCES F-33 financial return, meaning per-pupil spending can vary noticeably even between neighbouring campuses in the same city. Use the table to sort by enrollment, level, or district, then click any school name for campus-level demographics, Title I status, counselor and nurse staffing, AP courses, chronic-absenteeism rates, and district per-pupil spending. The sidebar links also connect COLONIA housing costs, wage data, and crime statistics — context many parents weigh alongside test-adjacent school signals when relocating.
Colonia High School accounts for 42.8% of all COLONIA public-school enrollment
That concentration — well above the 8.4% national median for largest-entity share — means COLONIA-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A dominant campus often anchors a city's program landscape and absorbs a disproportionate share of district capital and staffing decisions. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
COLONIA school enrollment varies 4.8× across entities
COLONIA school enrollment ranges from 282 students (lowest) to 1,354 students (highest), a spread of 1,072 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing, programme depth, and capital-renovation cycles often diverge inside the same city based on enrollment shape — a 200-student magnet runs a different operational model than a 2,000-student comprehensive high school.
COLONIA operates only 1 school district — among the most consolidated governance structures in the country
Most COLONIA school districts are a single unified district covering the whole city — a structural feature that simplifies inter-school comparison but concentrates policy authority. Consolidation produces narrower variance because resources pool across larger populations, but it can also mask intra-school district inequities — sub-school district differences within a single school district are not visible at this aggregation level. Consolidated systems typically rely more heavily on top-down funding formulas than on local revenue variability.
COLONIA student-teacher ratio is 11.8:1 — 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.
The top-rated school in COLONIA is Colonia High School with a quality score of 60/100. There are 6 public schools in COLONIA with 3,162 total students.
