Simi Valley Unified, CA - District Data

Original Research by School Decision on Simi Valley Unified

Simi Valley Unified serves a substantial student population across the Ventura County area in both elementary and secondary grades. The district's testing data shows areas of strength in English language arts, where proficiency rates hover around the midpoint or slightly above across grades three through eight. Mathematics performance is noticeably weaker, with proficiency rates declining as students advance through middle school; by eighth grade, proficiency drops to the lower end of the range. Science results track similarly to math, with proficiency around four in ten across the grades tested.

Among Ventura County's districts, Simi Valley sits above the midpoint overall when proficiency is averaged across subjects and grades. That said, the district's chronic absenteeism rate runs below the county median, meaning a higher proportion of students miss school regularly compared to peers elsewhere in the county. Per-pupil spending is in the middle range, on the upper side, suggesting the district invests at a level broadly consistent with regional norms.

The student body is diverse. Hispanic students make up a substantial plurality, while white students represent the second-largest group. Asian students and students of two or more races together account for a meaningful share. Race and ethnicity data is reported; however, free-or-reduced-price-lunch counts and English learner counts were not provided, so a parent looking to understand the full socioeconomic or language-support landscape should ask the district directly.

Housing in the Simi Valley area is moderately priced for Southern California, with median home values in the range typical of inland Ventura County communities. Rental costs in the district's area are moderate as well. The affordability picture is mixed: a monthly mortgage payment would run notably higher than median rent, but housing costs relative to local income suggest a manageable situation compared to many California metros.

Two significant changes recently took shape. Beginning in the 2024-25 school year, the district moved all sixth graders from elementary to middle school campuses, ending the prior option of keeping sixth grade in a smaller elementary setting. That structural shift removes a choice some families valued. At the same time, the district launched its first Dual Language Immersion program, with Spanish and English, starting at Arroyo Elementary in kindergarten and planning to add a grade level each year. Students completing the program as a cohort would flow through Sinaloa Middle School and Royal High School, creating a continuous bilingual pathway for families seeking that option.

The district is also pursuing a new facilities bond for the November 2026 ballot. A feasibility survey showed support above the threshold needed to pass, though residents are already paying off two existing bonds. Families relocating into the district should be aware this represents a likely property-tax consideration in the near term.
