National city placement

One campus shapes the city average

According to NCES CCD 2024-25, Los Alamos has more public-school enrollment than 33% of the 4,487 US cities in this directory. Los Alamos High enrolls 35.6% of Los Alamos's public-school students. That is enough concentration for one institution to pull the citywide enrollment, staffing, and Resource Index averages toward its own profile. The smaller campuses below should therefore be compared directly rather than inferred from the headline mean; their grade configurations and program footprints can be materially different even inside the same district.

Combined-grade campuses shape the local portfolio

3 of Los Alamos's 6 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.

Campus spread matters more than the city mean

The 18-point gap between Los Alamos Middle and Mountain Elementary shows the range hidden by Los Alamos's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.

City enrollment: Top 67%
School count: Top 79%
Resource Index average: 64th percentile
Teacher staffing: 61st percentile

Los Alamos High accounts for 35.6% of all Los Alamos public-school enrollment

That dominant concentration means Los Alamos-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.

Los Alamos school enrollment varies 3.9× across entities

Los Alamos school enrollment ranges from 305 students (lowest) to 1,181 students (highest), a spread of 876 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.

Los Alamos operates one school district — a single-district system

Los Alamos'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.

Los Alamos student-teacher ratio is 14.5:1 — 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 Los Alamos is typically wider than the Los Alamos-aggregate figure suggests.
