Summary:
Schools in ZIP code 91792 include three Telesis Academy of Science & Math, Giano Intermediate, and Hollingworth Elementary, serving grades K–8 across 1,466 students in Rowland Unified. In 2025–2026, all three schools were below California’s all-grades results in ELA, math, and science. Their average was 40% in ELA, 29% in math, and 26% in science, compared with 49%, 38%, and 36% statewide. The central takeaway is that every school trails the state in all three subjects, with the largest group-average gap in science at 10 points.
Telesis stands out in ELA and math, scoring 47% and 34%—10 and 6 points above the next-highest school in those subjects. Giano had the lowest all-grades results in both, at 36% in ELA and 25% in math. Science results were closer: Hollingworth led at 27%, followed by Giano at 26% and Telesis at 25%; all were well below the state’s 36%. SchoolDigger gives Telesis 3 stars and a 53rd-percentile statewide rank; Giano and Hollingworth have 2 stars and rank at the 35th and 36th percentiles, respectively.
Recent changes are mixed rather than consistently upward: from 2024–2025 to 2025–2026, the three-school average rose 1 point in math and 3 points in science, while ELA was nearly unchanged. Individual results varied: Hollingworth’s science score rose 11 points even as its math score fell 4, while Telesis and Giano improved in math by 5 and 3 points. Grade-level results also reveal exceptions to the overall picture: Telesis was 7 points above the state in both grade 3 ELA and math, and Hollingworth was 8 points above the state in grade 6 ELA. In 2024–2025, free/reduced lunch eligible was 82% at Telesis, 95% at Giano, and 73% at Hollingworth; student–teacher ratios were 23.8, 19.9, and 23.8, respectively. These figures do not follow a simple pattern with achievement, and SchoolDigger’s rankings have declined over the three reported ranking years for all three schools.
