Summary:
Castro Valley Unified includes 15 schools in the Castro Valley area: nine elementary schools, two middle schools, three high schools and one alternative school. The unweighted averages across schools with reported scores are above state results in all three subjects: 63% in ELA versus 49% statewide, 59% in math versus 38%, and 53% in science versus 36%. These averages combine different schools and grade spans, so they offer a broad picture rather than a like-for-like comparison. The most important takeaway is that above-state averages mask large differences among schools.
Jensen Ranch Elementary leads the All Grades results in ELA, math and science, with 89%, 84% and 74% proficient, respectively. At the other end, Redwood Continuation High reports 21%, 3% and 8%—gaps of 68 percentage points in ELA, 81 in math and 65 in science compared with Jensen. Among middle schools, Creekside Middle is ahead of Canyon Middle in every listed grade and subject; in grade 7, Creekside leads by 14 points in ELA and 28 in math. In 11th grade, Castro Valley High is about 40 points ahead of Redwood in each subject.
Recent changes are mixed: average science proficiency rose 7 points for schools reporting both years, compared with a 3-point state increase, while ELA and math averages were nearly flat and their advantages over the state narrowed. Individual schools moved in different directions: Vannoy Elementary gained 30 points in science while losing 8 in ELA; Palomares Elementary gained 25 in science but lost 9 in ELA. SchoolDigger rankings also show Jensen Ranch improving from 314th to 60th statewide between 2023–24 and 2025–26. For context, the schools report a free/reduced lunch eligible measure for 2024–25: 20% at Jensen, 55% at Castro Valley Elementary and 53% at Stanton Elementary; these figures describe student populations, not what causes results. Ratios vary too: Jensen has 23.3 students per teacher, Creekside 20.0 and Redwood 12.4.
