5 public K-12 schools in Lake Arrowhead 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, Lake Arrowhead has more public-school enrollment than 13% of the 4,487 US cities in this directory. Rim of the World Senior High enrolls 42.1% of Lake Arrowhead'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.
Secondary campuses occupy an unusually large share
2 of the 5 listed Lake Arrowhead schools are classified as high schools, a substantial share of the local portfolio. Advanced-course access, counseling, and graduation-stage staffing therefore have more weight in the city Resource Index average than they do in an elementary-heavy system.
A small portfolio contains radically different campus scales
Lake Arrowhead lists only 5 schools, yet reported enrollment runs from 44 to 860 students, a 20-fold range. In a portfolio this compact, the smallest record may be a specialized or nonstandard setting rather than a miniature version of the largest campus. That distinction affects how ratios and program fields should be read. Compare similarly configured grade levels first; combining the extremes into one city average conceals more than it explains.

Rim of the World Senior High accounts for 42.1% of all Lake Arrowhead public-school enrollment
That dominant concentration means Lake Arrowhead-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.
Lake Arrowhead school enrollment varies 20× across entities
Lake Arrowhead school enrollment ranges from 44 students (lowest) to 860 students (highest), a spread of 816 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.
Lake Arrowhead operates one school district — a single-district system
Lake Arrowhead'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.
Lake Arrowhead student-teacher ratio is 25.7:1 — well above typical (typically associated with unusually large scale or acute resource constraints)
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 Values this far above typical often signal acute resource constraints or a structurally different scale than most peers — worth reading alongside the underlying counts, not the ratio alone.
Most racially and ethnically mixed schools in Lake Arrowhead
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.
