District-Level NCES Analysis
Petaluma Joint Union High operates 10 public schools serving 4,926 students, placing it among the smaller districts in California. The school portfolio breaks down into 5 high, 3 middle, 1 elementary, 1 combined schools, a compact enough portfolio that families can compare every campus directly before they move, rent, or enrol. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Sonoma County.
Academic infrastructure includes 2 of 10 schools offering Advanced Placement (29 AP courses district-wide), a 234:1 student-counselor ratio, that meets the ASCA-recommended benchmark, and 19.1% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 58.7% White, 31.1% Hispanic or Latino, 2.1% Asian across the district's schools. Its most demographically mixed campus is Petaluma Accelerated Charter, with a diversity index of 61.9/100.
Its largest campus is Casa Grande High, enrolling 1,653 students (34% of the district's total enrollment). Its smallest is Carpe Diem High (Continuation), at 19 students, a 87x enrollment spread across the district's campuses.
Casa Grande High accounts for 33.6% of all Petaluma Joint Union High student enrollment
That dominant concentration means Petaluma Joint Union High-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
Petaluma Joint Union High school enrollment varies 87× across entities
Petaluma Joint Union High school enrollment ranges from 19 students (lowest) to 1,653 students (highest), a spread of 1,634 students. That ratio is an extreme outlier spread — among the widest gaps observed anywhere in this dataset. Per-school staffing ratios, programme availability, and capital-renovation cycles often diverge inside the same district based on enrollment shape.
Petaluma Joint Union High student-counselor ratio is 234:1 — low (typically associated with meeting or exceeding the American School Counselor Association (ASCA) recommended 250:1 benchmark, which correlates with stronger college and career counseling capacity)
student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment, districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
Petaluma Joint Union High chronic absenteeism rate is 19.1% — near the typical range (US average ~28) — aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism
chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement Variation between sub-units within Petaluma Joint Union High is typically wider than the Petaluma Joint Union High-aggregate figure suggests.
