Summary:
ZIP code 95901 has seven elementary schools, serving grade spans from K–5 to K–8; six are in Marysville Joint Unified, while Paragon Collegiate Academy is in its own district. Six schools have 2025–2026 results, and their average proficiency is below the state in English language arts (ELA), math, and science: 38%, 29%, and 23%, compared with 49%, 38%, and 36% statewide. The clearest takeaway is that the area-wide averages hide major differences between schools, with one school exceeding state results in two subjects.
Loma Rica is the strongest current all-grades performer: 61% in ELA and 47% in math, respectively 12 and 9 percentage points above state results, plus 33% in science, 3 points below the state. Covillaud also stands out in math at 43%, 5 points above the state. At the other end, Linda has the lowest ELA and math results, 21% and 13%, trailing the state by 28 and 25 points; Kynoch has the lowest science result, 11%, or 25 points below the state. Grade-level results add nuance: Loma Rica and Covillaud were notably strong in third-grade math, at 81% and 68%, compared with 47% statewide.
Results across the six schools were nearly flat from 2024–2025 to 2025–2026: average ELA remained 38%, while math and science remained 29% and 23% after rounding. State science rose from 33% to 36%, and the local average science gap widened from 10 to 13 points. SchoolDigger’s rankings also place Loma Rica highest among schools with current rankings, at the 68th percentile, and Linda lowest, at the 6th. Other factors do not line up neatly with results: Loma Rica has 115 students and a 19.1 student–teacher ratio, while Cordua has 77 students and a 17.1 ratio but lower ELA and math scores. Kynoch and Linda report similar free/reduced lunch eligible shares for 2024–2025—82%—yet their ELA and math results differ substantially. Paragon’s latest test results are from 2024–2025, so they are not included in the current-year comparisons.
