Annual results and the full academic record
Is it getting better · CAASPP 2019 to 2025

Climbed from the 42nd to the 80th percentile since 2019 — past roughly 2000 elementary schools.

Most rating sites would stop at “55% proficient” and call it done. Mary Collins Charter School at Cherry Valley deserves a closer read. One in four of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.

Mary Collins Charter School at Cherry Valley's low-income kids hit 54.5% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

As a charter, Mary Collins Charter School at Cherry Valley enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

325 tested · 3 of 3 grades published · cohort of 50 tracked

Mary Collins Charter School at Cherry Valley scores 53 of 100 on SchoolScope's Scope Score — the 80th percentile of 5,721 California elementary schools (CDE CAASPP 2025).

The road from this school ends at Petaluma High, which sent 28 graduates to UC campuses last fall and teaches 17 AP subjects. Those numbers describe past cohorts — a child starting here today would reach Petaluma High around 2035, and 10 years is a long time for a school to hold still, and by the state's 2023 count 79% of Petaluma High's graduates enrolled in college somewhere, UC or not.

What should I do next?

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 extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
  • 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.
Questions

Frequently asked questions

Is Mary Collins Charter School at Cherry Valley a good elementary school?
Mary Collins Charter School at Cherry Valley has a Scope Score of 53 out of 100, placing it in the 80th percentile of California elementary schools and ranked #1,145 statewide. 25.3% of students exceeded the state standard on the 2025 CAASPP assessment, which is 3.9 percentage points above the California average of 21.4%. The Scope Score weights 6 dimensions for elementary schools: exceeded standard (42%), met or exceeded (proficient) (23%), grade 3-to-5 growth (20%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Mary Collins Charter School at Cherry Valley's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 54.7% of students at Mary Collins Charter School at Cherry Valley met or exceeded the state standard in ELA and Math combined, and 25.3% exceeded it. The gap between those numbers matters: 29.4% of students are at the proficiency floor, while 25.3% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 342 student-subject combinations were assessed.
How does Mary Collins Charter School at Cherry Valley rank in California?
Mary Collins Charter School at Cherry Valley ranks #1,145 among California elementary schools by Scope Score, placing it in the 80th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), same-cohort growth (2023 G3 → 2025 G5), 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 Mary Collins Charter School at Cherry Valley getting better or worse?
SchoolScope follows the same cohort of students across grades rather than comparing two different grades in the same year. At Mary Collins Charter School at Cherry Valley that cohort is 2023 G3 → 2025 G5, measured in SBAC scale-score points. Its gain ranks strong among California elementary schools — roughly the 94th percentile, ahead of the typical school at this level. Read the ranking, not the raw point gain: scale scores rise with age, so nearly every school posts a positive number and only the relative position tells you anything. Growth is weighted at 20% in the elementary Scope Score because it is the least demographically confounded signal available — it tracks change over time rather than the level students arrived at. See full methodology.
What is the attendance and school culture like at Mary Collins Charter School at Cherry Valley?
14.0% of students at Mary Collins Charter School at Cherry Valley are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 2.0%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does Mary Collins Charter School at Cherry Valley compare to other schools in Petaluma?
Mary Collins Charter School at Cherry Valley scores 53/100 (80th percentile) among California elementary schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 494 students. Use the schools in Petaluma page or the map view to compare all elementary schools nearby.
How does Mary Collins Charter School at Cherry Valley serve low-income and underrepresented students?
At Mary Collins Charter School at Cherry Valley in Petaluma, 54.5% of low-income students met or exceeded the ELA standard in 2025, compared to 41.5% district-wide and 38.2% statewide. Mary Collins Charter School at Cherry Valley outperforms its district average for low-income students by 13.0 percentage points in ELA. Other subgroups: Low-Income students (41.4% Math proficient); White students (61.9% ELA proficient). The largest proficiency gap is 11.8 percentage points for low-income students. Data source: California Department of Education, CAASPP 2024-25. 88 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.

What the score weighs · CAASPP 2024–25

Growth carries this score — its returning cohort's growth from grade 3 to grade 5. The test levels clear the state's too.

The school's returning cohort — mostly, not exactly, the same kids two years on — gained 92 scale-score points across the span. Almost every school gains points, so we rank the gain against every other California school in this level.
