5 public K-12 schools in Friday Harbor 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, Friday Harbor has more public-school enrollment than 1% of the 4,487 US cities in this directory. Friday Harbor Elementary School enrolls 41.4% of Friday Harbor'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 Friday Harbor 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
Friday Harbor lists only 5 schools, yet reported enrollment runs from 6 to 329 students, a 55-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.

Friday Harbor Elementary School accounts for 41.4% of all Friday Harbor public-school enrollment
That dominant concentration means Friday Harbor-wide averages can mask substantial variation outside the largest entity. Grade level: Elementary. 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.
Friday Harbor school enrollment varies 55× across entities
Friday Harbor school enrollment ranges from 6 students (lowest) to 329 students (highest), a spread of 323 students. That ratio is among the widest observed and reflects extreme heterogeneity inside a single city, with small specialty programs listed alongside large comprehensive campuses. 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.
Friday Harbor operates one school district — a single-district system
Friday Harbor'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.
Friday Harbor student-teacher ratio is 17.6:1 — 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 Friday Harbor is typically wider than the Friday Harbor-aggregate figure suggests.
Most racially and ethnically mixed schools in Friday Harbor
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.
