In 2025–26, the equal-school averages were 47% in ELA, 35% in math and 31% in science, compared with state rates of 49%, 38% and 36%. The central finding is how sharply results vary: school scores span about 61 to 67 percentage points in each subject, with leading schools well above state rates and the lowest schools far below them.

Shannon Ranch Elementary led math at 67%, about 28 points above the state rate.

Among high schools, Redwood High had stronger ELA and science scores, 71% and 54%, but its 35% math result was below the state rate.
Average scores rose modestly from 2024–25 to 2025–26: about 1 point in ELA, 1 point in math and 2 points in science. But the state’s science rate rose by 3 points, so the schools’ average science gap widened by about 2 points. Individual results varied: Redwood High’s ELA score fell by 10 points, while Willow Glen Elementary’s science score fell by 8. SchoolDigger ranked Oak Grove at the 87th percentile and Denton and Shannon Ranch at the 85th percentile among California elementary schools; Highland was at the 5th. For context, 2024–25 free/reduced lunch eligibility was 36% at Denton and 33% at Oak Grove, compared with 87% at Highland; these figures are context, not an explanation of outcomes. Oak Grove’s student–teacher ratio was 25.8, while Highland’s was 18.2, another reminder that a lower ratio alone does not identify a higher-scoring school.
