Each level is scored on its own scale — elementary, middle, and high are never ranked against each other.

Stage 1 of 3

The elementary years

44 points separate Vista Elementary (66) from Berylwood Elementary (23) — at this level, which school matters more than which district.

0100
Strong Solid Developing Needs Support district avg state avg

44 points separate the strongest and weakest of these 19 elementary schools — the average hides more than it tells.

The strength

Vista Elementary (66/100) holds the Strong band — 46.3% of its students exceed the state standard, against a level average of 20.1%. 2 schools here rank as Growth Engines — returning cohorts gaining more than most schools statewide.

The catch

44 points separate the top and bottom elementary schools — the district average won't predict the school in front of you.

Stage 2 of 3

The middle years

The narrowest gate on the path: Hillside Middle at 42, then a 18-point drop to the next of 3 middle schools.

0100

3 middle schools span 20 points around an average of 29.5.

The strength

Hillside Middle is the strongest option at 42/100 — 17.5% of its students exceed the state standard.

The catch

2 of 3 middle schools sit in the Needs Support band — which campus you're zoned for carries real weight here.

Stage 3 of 3

The high school years

One school defines the top: Santa Susana High sits 18 points clear of the field — the other 3 high schools are a different conversation.

0100

56 points separate the strongest and weakest of these 4 high schools — the average hides more than it tells.

1 continuation/alternative school not plotted — it ranks within its own class, not on this statewide axis.

The strength

Santa Susana High (79/100) holds the Strong band — 40.2% of its students exceed the state standard, against a level average of 18.9%. 1 school classifies as Strong All-Around — no weak dimension we measure.

The catch

28.1% of students are chronically absent (state: 23.1%) — chronic means missing 10% or more of the school year. Whatever the scores say, ask each school what it is doing about attendance.

What it means for your family

If you're choosing a neighborhood

Compare schools at your child’s level before deciding on an address. The strongest attendance-zone candidate is Vista Elementary at 66/100 — confirm the exact boundary with the district before the house.

If you already live here

No charters or magnets among the ranked schools here, so the main lever is an intra-district transfer — California districts run them on their own windows and criteria. If your zoned school sits low in the appendix below, ask the district office for this year's dates.

If your kid is enrolled now

A band is a position, not a prophecy — 3 campuses here rank as Growth Engine (2) or On the Rise (1), their returning cohorts gaining more than most schools statewide. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.

The strongest-scoring run through the district:

Top scorers at each level — not necessarily one zoned sequence. Confirm feeder patterns and enrollment zones with the district, and visit before you decide.

What this page can't see: whether a campus feels safe and glad at 8 a.m. If a path above looks workable, the next step is a visit.

Frequently asked questions

How many schools are listed in Simi Valley Unified?
This SchoolScope directory lists 26 public schools in Simi Valley Unified with 2024–25 reporting records. This is directory coverage, not a complete campus inventory. Each school appears under its primary reporting level; a K–8 or K–12 campus may serve additional grades.

Among comprehensive public schools listed here, the highest Scope Score at each primary reporting level is: Elementary: Vista Elementary (66/100). Middle: Hillside Middle (42/100). High: Santa Susana High (79/100). These are separate level rankings, not a single cross-level league table. A score does not establish fit or enrollment eligibility. See the methodology.
Can I compare elementary, middle, and high schools directly?
Compare schools at the same level and within the same enrollment group. Scope Score formulas and available measures differ by level. The plots show comprehensive public schools separately for each level; individual profiles explain their comparison group.
Does living in Simi Valley Unified guarantee a particular school?
A district outline does not establish assignment to an individual school. Attendance boundaries, programs, permits, and available space can affect enrollment. Confirm the requirements directly with the district.
What does a SchoolScope pattern mean?
Archetypes summarize patterns in publicly reported academic and school-climate measures. They describe reported results, not a school’s quality or a child’s fit. Open the school profile for reporting years, missing measures, and questions to ask. Read how the patterns are defined.
Where do these results come from?
The underlying public data comes from the California Department of Education, including CAASPP reporting for 2024–25. Scope Scores and archetypes are SchoolScope calculations, not official CDE ratings. View CDE data and SchoolScope’s methodology and limitations.
