Summary:
High schools in ZIP code 95650 are represented by one school, Del Oro High, serving grades 9–12 and enrolling 1,634 students. With only one school in the area, its results are the area’s results. In 2025–26, it posted all-grades proficiency of 73% in English language arts (ELA), 56% in mathematics, and 56% in science, above state results in all three subjects; its largest advantage was in ELA, at 24 percentage points.
Del Oro High is both the top and bottom school in the local list by default, so there is no meaningful school-to-school comparison. Against the state, its 2025–26 proficiency was higher by 24 points in ELA (73% versus 49%), 18 points in mathematics (56% versus 38%), and 20 points in science (56% versus 36%). It also exceeded the Placer Union High district results in all three subjects. Completion and attendance measures were also favorable: graduation was 99%, compared with 88% statewide, while dropout was 1% versus 8% and chronic absenteeism was 9% versus 18%. Because this list has only one school, it cannot show variation among local schools.
Science was the clearest recent improvement: from 2024–25 to 2025–26, Del Oro High rose 8 percentage points in science proficiency, compared with a 3-point state increase, widening its state advantage by 5 points. ELA and mathematics changed little by comparison: school and state gains were each about 0 points in ELA and 1 point in mathematics, leaving those gaps essentially unchanged. SchoolDigger ranked the school 226th of 2,137 schools, at the 89th percentile, in 2025–26; its rank improved 18 places from the prior year, but was 119 places lower than in 2023–24, when it was at the 95th percentile. Other context includes a 24.2:1 student–teacher ratio and 13% free/reduced lunch eligible in 2024–25; these are observations about the school, not explanations for its results.
