Best Elementary Schools in Zip Code 93021

Elementary schools in zip code 93021 include six schools in Moorpark Unified: five serve kindergarten through grade 5, while Campus Canyon Elementary serves kindergarten through grade 8. In 2025–2026, the six-school averages were 57% in English language arts (ELA), 52% in math, and 46% in science, compared with California averages of 49%, 38%, and 36%. Because schoolwide results combine different grade spans, especially at Campus Canyon, comparisons for shared grades can add useful context. The key takeaway is that the area’s averages are above the state’s, but results vary substantially by school and subject.

Walnut Canyon Elementary leads schoolwide ELA and math, with 71% and 61% proficiency—about 22 and 23 points above the state, respectively. Its rates are 11 points higher in ELA and 6 points higher in math than the next-best school. Arroyo West Elementary leads science at 56%, 20 points above the state, while Flory Academy of Sciences and Technology is next at 52%. At the lower end, Flory has the lowest ELA result at 48%, about 2 points below the state, and math at 39%, roughly level with the state. Peach Hill Academy has the lowest science result at 34%, 2 points below the state. Grade-level results add a notable caution for Peach Hill: its grade-5 ELA, math, and science results are the lowest among the listed schools with those results.
