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

Has held the 86th-percentile line every tested year since 2019.

Most rating sites would stop at “59% proficient” and call it done. Gratton Charter deserves a closer read. It sits at the 86th percentile of 5,721 California elementary schools — but the ranking is the least interesting thing on this page.

The headline number: 5.2% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.

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

75 tested · 3 of 3 grades published · no cohort tracked

Gratton Charter scores 59 of 100 on SchoolScope's Scope Score — the 86th percentile of 5,721 California elementary schools (CDE CAASPP 2025).

This school hasn't fully recovered from the pandemic: 59% meet the standard today, versus 78% in 2019 — a gap worth asking about on a visit.

California’s growth results and student groups
State growth model · CDE growth model 2024–25

California's own growth model splits here — the 35th percentile in reading against the 89th in math, among elementary schools.

Context — never part of the Scope Score

California runs its own growth model — it follows individual children in grades 4 through 8 and compares each one against a prediction from their own prior scores. On that measure this school sits a little above the middle of California elementary schools in reading, and the 89th in math. We show it; we don't score it.

— pts vs expected is scale-score points above or below what California's model predicted for these same children from their own prior-year scores. It is not a percentage and not a percent of anything. A typical California elementary school lands at +2 in reading, and the middle half of them fall between −5 and +9 — the spread is wide, so read the rank, not the sign. CDE blends two consecutive years into each published figure, so adjacent years share input data and no year-over-year trend can honestly be drawn from them. It covers grades 4-8 only, and it is not part of the Scope Score — we assessed it and left it out: it tracks school demographics roughly three times as strongly as our own growth measure does, and one published year is not enough to test how stable it is.

California follows these children individually and predicts each one's score from their own prior year. Each row is read against the same group at a typical California elementary school — not against zero, and not against this school's all-students figure, because the state's expectation already differs by group.

— 2 more groups are reported here with between 11 and 29 students. We hold those back on purpose: at that size the figure swings about 17 points on its own, and a quarter of such groups land past the state's top or bottom cut point by chance alone. They are listed with their student counts in the data appendix. — A group not listed at all had fewer than 11 students with a growth score, so California published nothing for it here. That is a privacy protection, not a judgment about those students. — Context only. None of this enters the Scope Score.

Worth knowing

At 111 students, this school is much smaller than the typical California elementary school (≈480).

On the state's science test (CAST), 58% met or exceeded the standard — science is tested in grades 5 and 8 and once in high school, and it never enters the Scope Score.

What should I do next?

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.
Questions

Frequently asked questions

Is Gratton Charter a good elementary school?
Gratton Charter has a Scope Score of 59 out of 100, placing it in the 86th percentile of California elementary schools and ranked #806 statewide. 38.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 17.1 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 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% 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. 74 student-subject combinations were assessed.
How does Gratton Charter rank in California?
Gratton Charter ranks #806 among California elementary schools by Scope Score, placing it in the 86th 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.
What is the attendance and school culture like at Gratton Charter?
5.2% of students at Gratton Charter are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 0.5%, 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 Gratton Charter compare to other schools in Denair?
Gratton Charter scores 59/100 (86th 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 111 students. Use the schools in Denair page or the map view to compare all elementary schools nearby.
How does Gratton Charter serve low-income and underrepresented students?
At Gratton Charter in Denair, 57.1% of white students met or exceeded the ELA standard in 2025, compared to 53.8% district-wide and 61.8% statewide. Gratton Charter outperforms its district average for white students by 3.3 percentage points in ELA. Other subgroups: White students (57.1% Math proficient). Data source: California Department of Education, CAASPP 2024-25. 35 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.

A closer look at the evidence

Gratton Charter: reading the evidence

Gratton Charter posts 59% meeting the standard, and 38.5% 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.

Subject proficiency describes tested students, while graduation describes a graduating cohort. These figures are not successive stages followed by the same students.

Ask about what we don't score — class size, electives, the feel of a classroom — strong numbers everywhere on paper don't mean every classroom feels the same.

Whole scale-score points above or below what CDE's model predicted for these same children from their own prior-year scores — not a percentage, not a percentile. Statewide a typical school lands near +1 with a spread of about 13 points either side, so read a figure against its group's own typical value, not against zero. Muted rows have fewer than 30 students with a growth score — published by CDE, held back from the narrative sections above because at that size the figure swings about 17 points on its own. “Not categorised” is CDE assigning no band — English Only, Recently Reclassified, and English Learners Only receive a value and no band, for every school in the state. It is not a missing number. Most figures blend two consecutive years, so adjacent published years share input data and no trend line can honestly be drawn across them. A group absent from this table had fewer than 11 students with a growth score and was never published. Grades 4-8 only. None of this enters the Scope Score — it is more strongly correlated with school demographics than our own growth measure, and one published year is not enough to test its reliability.
