11 public K-12 schools in Bloomfield 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, Bloomfield has more public-school enrollment than 66% of the 4,487 US cities in this directory. Bloomfield sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
The school portfolio is elementary-weighted
7 of Bloomfield's 11 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
Bloomfield's average Resource Investment Index sits at the 53rd percentile, while its teacher-staffing measure sits at the 89th percentile. The 36-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.

Bloomfield High School accounts for 32.1% of all Bloomfield public-school enrollment
That dominant concentration means Bloomfield-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.
Bloomfield school enrollment varies 13× across entities
Bloomfield school enrollment ranges from 158 students (lowest) to 2,055 students (highest), a spread of 1,897 students. That spread reflects typical urban portfolio variation between specialty programs and large neighbourhood schools. 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.
Bloomfield operates one school district — a single-district system
Bloomfield'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.
Bloomfield 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.
Most racially and ethnically mixed schools in Bloomfield
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.
Which Bloomfield school has the highest Resource Investment Index? ▼

How many schools are in Bloomfield, NJ? ▼
Bloomfield has 11 public schools with a total enrollment of 6,400 students. 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.
