Summary:

The nine schools in Oakley Union Elementary serve Oakley students in seven elementary schools (grades K–5) and two middle schools (grades 6–8). In 2025–26, elementary-school averages were 34% proficient in ELA, 30% in math and 23% in science, each below the state rates of 49%, 38% and 36%. Middle-school averages were 36% in ELA, 16% in math and 18% in science, also below state rates. The clearest overall finding is that elementary results vary considerably from school to school, while middle-school math is especially low: the middle-school average is 23 percentage points below the state rate.

Different elementary schools lead in each subject: Gehringer Elementary leads ELA at 42%, Almond Grove Elementary leads math at 39%, and Summer Lake Elementary leads science at 33%. At the other end, Laurel Elementary has the lowest ELA result at 22% and science result at 11%; Oakley Elementary is lowest in math at 23%. The top-to-bottom gaps are 20 percentage points in ELA, 16 in math and 22 in science. The middle schools are much closer to each other: Delta Vista Middle is ahead of O’Hara Park Middle by less than 1.3 percentage points in every subject. SchoolDigger ranks Gehringer at the 47th percentile among elementary schools, compared with Laurel at the 18th; Delta Vista is at the 25th percentile and O’Hara Park at the 23rd.

Elementary averages declined from 2024–25 to 2025–26 by 3 percentage points in ELA, 2 in math and 1 in science, even as state rates rose in all three subjects. Middle-school ELA improved by 2 points on average, while middle-school math and science each fell by about 1–2 points. Almond Grove had the largest elementary declines, falling 9 points in ELA, 10 in math and 8 in science; Oakley moved against that pattern, gaining 5 points in ELA and 3 in math. As context, all nine schools report free/reduced lunch eligible (FRL) for 2024–25: elementary shares range from 36% at Almond Grove to 54% at Oakley. Reported student–teacher ratios range from 21.0 at Oakley to 24.5 at Iron House Elementary; these figures offer context, not an explanation for test results.
