National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Oakland has more public-school enrollment than 19% of the 4,487 US cities in this directory. Southern Garrett High School enrolls 36.1% of Oakland'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
Oakland's list includes 2 elementary, 1 middle, and 1 high-school campus, plus 2 combined-grade records. 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
Oakland lists only 6 schools, yet reported enrollment runs from 54 to 870 students, a 16-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.
