Summary:
Zip code 91351 has nine schools—six elementary, two middle and one high school—serving 6,777 students across several school districts. Enrollment ranges from 380 students at Cedarcreek Elementary to 1,952 at Canyon High. The clearest takeaway is that results vary substantially from school to school, especially among the elementary schools.
In 2025–2026, Canyon High had the highest All Grades results: 81% proficient in English language arts (ELA) and 64% in math, respectively 32 and 26 percentage points above the state figures. Rio Vista Elementary led science at 57%, 21 points above state; among elementary schools, Leona H. Cox Community Elementary led ELA at 57%, while Cedarcreek Elementary led math at 51%. At the other end, Canyon Springs Community Elementary was lowest in all three subjects, with 37% in ELA, 32% in math and 22% in science—12, 6 and 14 points below state, respectively.
Across the nine schools, average results from 2024–2025 to 2025–2026 fell 2 percentage points in ELA, rose 2 in math and rose 5 in science. The average school-to-state lead narrowed in ELA from 6 points to 4, while widening in math from 6 to 7 and science from 1 to 3. SchoolDigger rankings also show gains for Canyon High, from the 77th to the 92nd percentile over three years, and La Mesa Junior High, from the 65th to the 76th. All schools report free/reduced lunch eligible figures for sy 2024–2025: Canyon Springs was 82%, Cedarcreek 83% and Rio Vista 77%, illustrating that this measure alone does not sort schools by results. Because schools serve different grade spans, All Grades results are not fully like-for-like; grade-matched comparisons offer a fairer view where available.
