Simi Valley High: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.

Simi Valley posts 15.9% exceeding the standard — versus 15.8% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.

ranked #547 statewide · #3 of 5 in Simi Valley Unified

Simi Valley High scores 55 of 100 on SchoolScope's Scope Score — the 75th percentile of 2,160 California high schools (CDE CAASPP 2025).

🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.

CDE CAASPP 2025

Most rating sites would stop at “37% proficient” and call it done. Simi Valley deserves a closer read. The school sits in Simi Valley, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 84.1% of students leave measurably college-ready, versus 35.4% statewide.

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

  • Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
  • Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
  • Ask how the school communicates with families when a child starts to struggle.
  • Ask what a typical day looks like for a new student in the first few weeks.
