Summary:
Royal Valley has one listed high school, Royal Valley High, serving grades 9–12 and enrolling 223 students. Its 2025–26 proficiency was below state results in all three subjects: 36% in English language arts (ELA) versus 46% statewide, 33% in math versus 41%, and 27% in science versus 38%. The most important finding is that science had the school’s largest all-grades gap with the state—11 percentage points.
There is no meaningful top-to-bottom school comparison because this list contains only one high school. Within Royal Valley High, ELA was the strongest subject and science the weakest; compared with Royal Valley district results, the school was lower by 6 percentage points in ELA, 6 in math, and 11 in science. Grade-matched gaps with the state were smaller, ranging from 3 to 4 points. Some other indicators compare more favorably with the state: graduation was 91% versus 90%, dropout was 0.4% versus 1.2%, and chronic absenteeism was 10.8% versus 17.8%; against the district, graduation matched, while dropout and absenteeism were slightly higher.
Recent academic changes were mixed: from 2024–25 to 2025–26, ELA proficiency fell 2 percentage points at the school while rising 1 point statewide, whereas math rose 6 points at the school and 2 statewide. As a result, the average gap to the state across those two subjects remained about 9 points. SchoolDigger’s ranking also fell over the three reported years, from the 83rd percentile and 4 stars in 2023–24 to the 38th percentile and 2 stars in 2025–26 (rank 212 of 340), even as math improved in the latest year. The school’s student–teacher ratio is 9.3, and 38% of students qualified for free or reduced-price lunch in 2024–25; these figures describe the school’s context but cannot be compared with local peer schools.
