8 public K-12 schools in Arroyo Grande 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, Arroyo Grande has more public-school enrollment than 52% of the 4,487 US cities in this directory. Arroyo Grande High enrolls 43.1% of Arroyo Grande'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.
A full K–12 ladder sits inside the city boundary
Arroyo Grande's list includes 3 elementary, 2 middle, and 2 high-school campuses, plus 1 combined-grade record. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
A small portfolio contains radically different campus scales
Arroyo Grande lists only 8 schools, yet reported enrollment runs from 96 to 2,012 students, a 21-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.

Arroyo Grande High accounts for 43.1% of all Arroyo Grande public-school enrollment
That dominant concentration means Arroyo Grande-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.
Arroyo Grande school enrollment varies 21× across entities
Arroyo Grande school enrollment ranges from 96 students (lowest) to 2,012 students (highest), a spread of 1,916 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.
Arroyo Grande operates one school district — a single-district system
Arroyo Grande'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.
Arroyo Grande student-teacher ratio is 19.4:1 — 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 Arroyo Grande
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.
