Summary:
ZIP code 93432 has one listed school, Creston Elementary, serving kindergarten through fifth grade and enrolling 61 students. The available results show different performance by grade, so families can look beyond the all-grade averages. In 2025–2026, the school’s all-grade ELA proficiency was 41% and math was 34%, compared with 49% and 38% statewide. The most important finding is that Creston Elementary was below state results in both subjects, with the larger gap in ELA.
There is no top or bottom school within this ZIP-code list because Creston Elementary is the only one. Its ELA result was 9 percentage points below the state and 10 below Atascadero Unified; math was 4 points below both. Grade-level results reveal a notable exception and a concern: fourth-grade ELA nearly matched the state, at 46% versus 46%, while third-grade ELA was 17 points below and third-grade math was 29 points below state results. Chronic absenteeism was 16%, lower than the district’s 17% and the state’s 18% in 2025–2026.
Math changed much more than ELA over time: the all-grade math result fell 17 percentage points, from 52% in 2024–2025 to 34% in 2025–2026, shifting from 15 points above the state to 4 points below it. ELA stayed essentially flat at 41% across those years, while the state improved slightly, widening the school’s shortfall by about 1 point. SchoolDigger rates Creston Elementary 2 stars and places it at the 37th percentile for 2025–2026; earlier reported rankings were at the 63rd percentile in 2017–2018 and 50th in 2018–2019. The student-teacher ratio was 20.3:1 in 2024–2025, and 46% of students were reported as free/reduced lunch eligible that school year. With only one school listed and some grade-level results based on small groups, the data cannot show differences between schools in the ZIP code.
