Simi Valley public schools are rated primarily through the California School Dashboard, the state's official accountability system, plus standardized assessment results. Many Simi Valley Unified School District campuses post scores at or above state averages as of 2026.
Who rates schools and what the ratings mean
The official rating system for California schools is the California School Dashboard, published by the California Department of Education. It uses color-coded performance levels (blue, green, yellow, orange, red) across measures such as academic achievement, graduation rates, chronic absenteeism, and progress for English learners.
Standardized testing through the California Assessment of Student Performance and Progress (CAASPP) measures English language arts and math proficiency. Together, the Dashboard and CAASPP give the most authoritative, publicly verifiable picture of school performance.
Third-party sites like GreatSchools also publish ratings, but their scores blend test data with other inputs and methodologies vary. Treat them as a starting point and verify against the state sources.
How Simi Valley Unified School District performs
The Simi Valley Unified School District (SVUSD) serves most of the city across elementary, middle and high school campuses. As of 2026, many SVUSD schools post Dashboard results and CAASPP proficiency rates that meet or exceed California state averages.
Performance varies campus by campus, as it does in every district. Some schools rate higher in math, others in English language arts. The district also offers specialized and magnet-style programs, so look at the specific school, not just the district average.
How to read school ratings without being misled
What I tell clients: a school rating is a snapshot, not a verdict. A few practical rules help. First, look at the underlying data on the Dashboard, not just a single composite score. Second, check trends over several years rather than one.
Third, remember that ratings correlate strongly with factors outside the school's control. A score is a useful data point, but visiting the campus, talking to the office, and looking at specific programs tells you things a number cannot.
Finally, verify boundaries. Two homes a few blocks apart can feed into different schools. Never assume.
Verifying ratings for a specific home
Here is where to confirm the schools tied to any address you are considering:
| Source | What to check |
|---|---|
| California School Dashboard | Official performance levels and trends |
| CAASPP results portal | Math and English proficiency rates by school |
| SVUSD school locator | Confirm attendance area for a specific address |
| School site visit | Programs, facilities and office staff |
Why school ratings affect resale value
School quality is one of the most durable drivers of buyer demand. Homes in well-regarded attendance areas tend to hold value and sell faster, because they appeal to the large pool of buyers with children.
Even buyers without kids care, because they know future resale depends on it. When I price a Simi Valley home, the attendance area is one of the factors I account for, the same way square footage and condition are.
