Del Rey Elementary scores 44 of 100 on SchoolScope's Scope Score — the 55th percentile of 5,744 California elementary 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.

Most rating sites would stop at “32% proficient” and call it done. Del Rey deserves a closer read. The school sits in San Lorenzo, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

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 how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
  • 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.

What are Del Rey Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 31.7% of students at Del Rey Elementary met or exceeded the state standard in ELA and Math combined, and 13.9% exceeded it.

How does Del Rey Elementary rank in California?

Del Rey Elementary ranks #2,611 among California elementary schools by Scope Score, placing it in the 55th percentile.

Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.

Is Del Rey Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Del Rey Elementary increases by 1.3 percentage points from Grade 3 to grade 5 growth.
