17 public K-12 schools in Cerritos 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, Cerritos has more public-school enrollment than 84% of the 4,487 US cities in this directory. Cerritos's average Resource Investment Index ranks above most listed cities even though its student-teacher ratio is on the more crowded side of the national city distribution. That is a useful mismatch, not a contradiction: counselor access, gifted programs, and attendance can lift the composite while classroom staffing remains comparatively tight. Families should inspect the component scores on each school profile instead of reading the city index as a shorthand for small classes.
The school portfolio is elementary-weighted
10 of Cerritos's 17 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 3 middle and 3 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
Cerritos's average Resource Investment Index sits at the 69th percentile, while its teacher-staffing measure sits at the 8th percentile. The 61-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.

Cerritos High accounts for 17.3% of all Cerritos public-school enrollment
That concentration means Cerritos-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.
Cerritos school enrollment varies 27× across entities
Cerritos school enrollment ranges from 74 students (lowest) to 1,996 students (highest), a spread of 1,922 students. That spread is wider than typical and predicts noticeable gaps in service quality between the highest and lowest areas. 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.
Cerritos operates one school district — a single-district system
Cerritos'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.
Cerritos student-teacher ratio is 22.1:1 — high (typically associated with larger urban scale or staffing constraints that have widened the headcount gap)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
Most racially and ethnically mixed schools in Cerritos
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.
