Summary:
ZIP code 94551 has six elementary-level schools in the Livermore Valley Joint Unified School District: five serve kindergarten through grade 5, while Junction K-8 serves kindergarten through grade 8. In 2025–2026, the six schools’ average proficiency was above the state result in all three subjects, with the largest advantage in math: 54% versus 38%, or 15 percentage points. The most important finding for families is that results differ substantially from school to school, especially in math.
Lawrence Elementary led all-grades results in every subject, with 77% proficient in ELA, 79% in math, and 63% in science—28, 41, and 27 points above the state, respectively. Altamont Creek Elementary was next strongest across the three subjects, at 69%, 63%, and 56%. At the lower end, Marylin Avenue Elementary had the lowest ELA and science results, 41% and 26%; Junction had the lowest math result, 28%. The top-to-bottom gaps were 36 points in ELA, 51 in math, and 37 in science.
Recent changes were mixed, with science the clearest concern: the six-school average fell 7 points from 2024–2025 to 2025–2026, while ELA was essentially unchanged and math rose 1 point. Science declined 18 points at Leo R. Croce Elementary and 11 at Lawrence, while Altamont Creek improved 4 points. SchoolDigger gives Lawrence five stars and a statewide rank of 322 out of 5,804, at the 94th percentile; its top results do not coincide with the lowest reported student-teacher ratio, as Lawrence’s was 23.5 in 2024–2025, compared with Croce’s 19.1. All six schools report free/reduced lunch eligible shares for school year 2024–2025: Lawrence’s 13% is close to Altamont Creek’s 16% and Rancho Las Positas Elementary’s 16%, though Lawrence’s results are higher; these figures are context, not an explanation of outcomes. All-grades results include schools with different grade spans, and the reported patterns do not establish causes.
