Gratton Charter scores 68 of 100 on SchoolScope's Scope Score — the 90th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

🚀 Growth Engine — Ask how the school tracks each kid's growth year to year, and what happens when a kid stalls instead of gaining.

Most rating sites would stop at “59% proficient” and call it done. Gratton Charter deserves a closer read. It sits at the 90th percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.

The headline number: +12.5pp separates this year's grade 3 from its grade 5. The state average rises 4.5pp over the same span. Following the same students from 2023 G3 → 2025 G5 points the same way.

As a charter, Gratton Charter enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

Worth a school visit

Ask what changed — new curriculum, new principal, new program. Momentum has a cause, and a visit will find it.

  • Ask how teachers track each child's growth over the year, not just where the class lands on test day.
  • 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 Gratton Charter's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 58.9% of students at Gratton Charter met or exceeded the state standard in ELA and Math combined, and 38.5% exceeded it. The gap between those numbers matters: 20.4% of students are at the proficiency floor, while 38.5% pushed past it. Most rating sites report only the combined "proficient" number.

How does Gratton Charter rank in California?

Gratton Charter ranks #550 among California elementary schools by Scope Score, placing it in the 90th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 growth), chronic absenteeism, and suspension rate. 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 Gratton Charter getting better or worse?

Based on 2025 CAASPP data, proficiency at Gratton Charter increases by 12.5 percentage points from Grade 3 to grade 5 growth. This upward trajectory suggests the school is adding measurable value — students leave with higher proficiency rates than they entered with.

SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
