Summary:
ZIP code 95123 has 15 schools: nine elementary schools, one middle school and five high schools. Thirteen have 2025–26 test results; the other two have 2024–25 results. Scores vary widely across the area, so a ZIP-code average does not describe the experience at any one school. The most important finding is that school-specific results differ sharply, especially among high schools.
Herman (Leonard) Intermediate leads current all-grades results in ELA and math, with 70% and 62% proficient; Indigo leads science at 70%. At the other end, Calero High has the lowest all-grades ELA and science results, at 14% and 4%, while Phoenix High has the lowest math result, 0%. The more comparable 11th-grade results also set Santa Teresa High apart: it is above the state by 9 points in ELA, 14 in math and 20 in science. Oak Grove High is below the state by 3–5 points across those subjects, while Calero and Phoenix are further below.
Across 13 schools with year-to-year comparisons, average results rose by 1 percentage point in ELA, 1 in math and 5 in science, but individual schools had both gains and declines. SchoolDigger ranks Sakamoto Elementary and Taylor (Bertha) Elementary alongside Herman, Santa Teresa and Indigo in the statewide top quartile; Allen at Steinbeck, Anderson, Calero and Phoenix are in the bottom quarter. As context, in 2024–25 the reported low-income measure was free/reduced lunch eligible, ranging from 17% at Discovery Charter II to 69% at Allen; these figures describe school context, not the reason for results. All-grades comparisons combine different grade spans, so the 11th-grade figures are a fairer comparison among high schools.
