13 public K-12 schools in Placerville 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, Placerville has more public-school enrollment than 69% of the 4,487 US cities in this directory. Sky Mountain Charter enrolls 36.1% of Placerville'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.
The school portfolio is elementary-weighted
7 of Placerville's 13 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 2 middle and 1 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
Campus spread matters more than the city mean
The 30-point gap between Sky Mountain Charter and Sutters Mill shows the range hidden by Placerville'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.

Sky Mountain Charter accounts for 36.1% of all Placerville public-school enrollment
That dominant concentration means Placerville-wide averages can mask substantial variation outside the largest entity. Grade level: Combined. 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.
Placerville school enrollment varies 21× across entities
Placerville school enrollment ranges from 117 students (lowest) to 2,511 students (highest), a spread of 2,394 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.
Placerville operates 7 school districts — among the most fragmented governance structures in the country
Each school district has independent budgeting, hiring, and service delivery authority. The fragmentation reflects historical patterns of inter-municipal boundary lines that pre-date modern city growth, students in different parts of the same city can attend different districts with different per-pupil spending, calendars, and graduation requirements. Per-region variation is largest in fragmented systems because each school district sets its own budget, contracts, and priorities without higher-level coordination above the regulatory floor.
Placerville student-teacher ratio is 19.2:1 — 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.
15% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.
