Summary:
Nine schools in 91748 are part of Rowland Unified: five elementary schools, an intermediate school and three high schools, serving students across the K–12 years. Among the eight schools with 2025–26 test results, the simple school average was 46% in ELA and 33% in science, both below state figures of 49% and 36%; math averaged 39%, about even with the state’s 38%. The most important finding is how sharply results differ from one school to another, with standout results at one end and very low scores at the other.
Shelyn Elementary leads the elementary group, with 71% ELA, 68% math and 53% science; its ELA and math results are 29 and 33 percentage points above the other schools’ averages. John A. Rowland High leads science at 53% and also scores 62% in ELA and 44% in math. At the lower end, Rowland Elementary scores 20% in ELA, 12% in math and 8% in science; Santana High (Continuation) records 15% in ELA and 2% in math. The elementary contrast also appears within the same grade: in fifth grade, Shelyn scored 70% in ELA and 55% in math, compared with 15% and 5% at Rowland Elementary.
Recent changes are mixed: across the same eight schools, average ELA fell 2 percentage points from 2024–25, while science rose 5 points and math rose 1 point. SchoolDigger’s ranking puts Shelyn at the 87th percentile, up from the 77th in 2023–24; Santana fell from the 25th to the 12th percentile. The reported measure for all nine schools is free/reduced lunch eligible for 2024–25: 64% at Shelyn, compared with 91% at both Jellick Elementary and Santana; these figures provide context, not an explanation for results. Ratios also do not form a simple performance ladder: Shelyn reports 21.8 students per teacher, Jellick 19.4 and Santana 10.3. Results are not fully like-for-like across school types, and Rowland Unified Community Day has no test scores listed.
