Summary:
ZIP code 94551 has seven schools in the Livermore Valley Joint Unified district: six schools serving elementary grades, including one K–8 school, and one middle school. In 2025–26 results, the elementary group’s average was above the state in all three matched grade 3–5 subjects, with the largest average advantage in math at 13 percentage points. The clearest finding is that Lawrence Elementary leads the elementary schools most consistently in grade-matched results.
Lawrence led the elementary schools in ELA and math in grades 3, 4 and 5, and in grade 5 science; in grade 4 math, it scored 81% compared with 34% at Junction K-8, a 46-point gap. Altamont Creek Elementary is another strong option in the reported results and is the only other elementary school above the state in all three all-grade subjects. Among middle grades, Andrew N. Christensen Middle outscored Junction in every matched ELA and math grade; its largest lead was 30 points in grade 6 ELA. Junction’s middle-grade math results are particularly low, while Marylin Avenue Elementary shows a different pattern: its grade 3 math result was 50%, above the state’s 47%, despite weaker ELA and science results. All-grade figures combine different grade spans, so grade-matched comparisons are more useful for comparing schools.
Recent changes are mixed: Altamont Creek improved in all three all-grade subjects from 2024–25 to 2025–26, while Rancho Las Positas Elementary and Leo R. Croce Elementary declined in all three. Science is the main concern across the area: six of seven schools fell, and the group average dropped 6 points, from 48% to 42%, while the state result rose from 33% to 36%. SchoolDigger’s 2025–26 percentile ranking places Lawrence at the 94th percentile and Junction at the 42nd; these rankings are separate from test scores. For context, in 2024–25, free/reduced lunch eligible students made up 13% at Lawrence and 52% at Marylin. Those figures describe school context, not a cause of results, and schools with similar shares can have different outcomes.
