Summary:
ZIP code 95203 has five Stockton Unified schools: three K–8 schools and two high schools serving grades 9–12. In 2025–26, their unweighted average proficiency was 36% in English language arts (ELA), 15% in math, and 21% in science, compared with state rates of 49%, 38%, and 36%. Because the schools serve different grade spans, their all-grades results are not direct grade-for-grade comparisons. The clearest shared concern is math: the group average was 24 percentage points below the state, and no school reached the state rate.
Health Careers Academy stands out in ELA and science, with 60% and 42% proficiency—the highest rates in the group and 11 and 6 points above the state. Its math rate, however, was just 12%. Weber Institute led in math at 20%, but remained 18 points below the state. At the other end, George Washington Elementary had the lowest math and science rates, at 6% and 3%. Among the K–8 schools, Victory Elementary was ahead of Spanos (Alex G.) Elementary in all-grades ELA and math, while Spanos led in science. Grade-level results can differ: George Washington’s fifth-grade ELA was 47%, close to the state’s 49%.
Group averages fell from 2024–25 to 2025–26: ELA by 8 points, math by 1, and science by 1, while state rates rose in all three subjects. There were exceptions: George Washington’s ELA increased by 7 points, and Weber’s math rose by 9, even as Health Careers’ ELA fell by 19 and its math by 11. SchoolDigger’s ranking for Weber also moved from the 77th to the 42nd percentile over three years. Context measures show differences, not explanations: 2024–25 free/reduced lunch eligible rates were 86% at Victory and 92% at Spanos, whose student–teacher ratios were 23.9 and 29.9. Their enrollments were nearly identical, at 484 and 482 students.
