Dunham Charter · Petaluma

Dunham Charter: Most kids here clear the bar, year after year. The question is what happens after that.

Dunham Charter posts 64% meeting the standard, and 36.4% going well past it. Most kids here keep up. Fewer get pushed further. Ask the school what it does for a child who already finds the work easy.

ranked #870 statewide

Dunham Charter scores 62 of 100 on SchoolScope's Scope Score — the 85th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

🚀 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 “64% proficient” and call it done. Dunham Charter deserves a closer read. The school sits in Petaluma, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

As a charter, Dunham 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 how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.

  • 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 gets spent here

Per-pupil spendingPer-pupil spending: $13,224, CA average $14,815$13,224 · spent at this school

These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.

Transitional kindergarten is offered here — confirmed by actual Census Day enrollment, not just the listed grade span.

On the state's science test (CAST), 44% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

The gap between those numbers matters: 27.4% of students are at the proficiency floor, while 36.4% pushed past it. Most rating sites report only the combined "proficient" number.

How does Dunham Charter rank in California?

Dunham Charter ranks #870 among California elementary schools by Scope Score, placing it in the 85th 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 Dunham Charter getting better or worse?

Based on 2025 CAASPP data, proficiency at Dunham Charter increases by 7.4 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.
