9 public K-12 schools in Marrero 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, Marrero has more public-school enrollment than 71% of the 4,487 US cities in this directory. Marrero'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.
Combined-grade campuses shape the local portfolio
6 of Marrero's 9 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.
High measured need meets a thin staffing ratio
Marrero's reporting schools show 69.4% free-lunch eligibility across measured enrollment, alongside an average 24.1:1 student-teacher ratio. These are separate constraints: one describes the economic context of enrolled students and the other compares student and teacher headcounts. The 21-point gap between Lincoln School for the Arts and L.W. Higgins High School is therefore more useful than the city mean alone. A school with a similar ratio may still report different counselor access, attendance, or gifted-program availability, so open the campus records before drawing conclusions about student support.

John Ehret High School accounts for 25.3% of all Marrero public-school enrollment
That concentration means Marrero-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.
Marrero school enrollment varies 4.5× across entities
Marrero school enrollment ranges from 414 students (lowest) to 1,850 students (highest), a spread of 1,436 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 sits between 62.5% and 75%, above a simple majority but below the highest descriptive band used here. 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.
Marrero operates one school district — a single-district system
Marrero'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.
Marrero student-teacher ratio is 24.1:1 — 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 Marrero
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:
verify current enrollment, attendance boundaries, and programs with the school district before acting. See the guide to understanding NCES data.
