Is it getting better · CAASPP 2019 to 2025

Has held the 82nd-percentile line every tested year since 2019.

Most rating sites would stop at “57% proficient” and call it done. Rocketship Mosaic deserves a closer read. Two-thirds of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.

Rocketship Mosaic's low-income kids hit 54.3% 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, Rocketship Mosaic enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

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

Rocketship Mosaic Elementary scores 55 of 100 on SchoolScope's Scope Score — the 82nd percentile of 5,721 California elementary schools (CDE CAASPP 2025).

This school hasn't fully recovered from the pandemic: 57% meet the standard today, versus 69% 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 45th percentile in reading against the 71st 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 71st 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.

— 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 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 what changes between grade 3 and grade 5 here, and who teaches the older kids.
  • 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 Rocketship Mosaic Elementary a good elementary school?
Rocketship Mosaic Elementary has a Scope Score of 55 out of 100, placing it in the 82nd percentile of California elementary schools and ranked #1,024 statewide. 32.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 11.2 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 Rocketship Mosaic Elementary's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 56.6% of students at Rocketship Mosaic Elementary met or exceeded the state standard in ELA and Math combined, and 32.5% exceeded it. The gap between those numbers matters: 24.1% of students are at the proficiency floor, while 32.5% 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. 463 student-subject combinations were assessed.
How does Rocketship Mosaic Elementary rank in California?
Rocketship Mosaic Elementary ranks #1,024 among California elementary schools by Scope Score, placing it in the 82nd 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 Rocketship Mosaic Elementary?
6.5% of students at Rocketship Mosaic Elementary are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 0.1%, 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 Rocketship Mosaic Elementary compare to other schools in San Jose?
Rocketship Mosaic Elementary scores 55/100 (82nd 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 528 students. Use the schools in San Jose page or the map view to compare all elementary schools nearby.
How does Rocketship Mosaic Elementary serve low-income and underrepresented students?
At Rocketship Mosaic Elementary in San Jose, 54.3% of low-income students met or exceeded the ELA standard in 2025, compared to 33.1% district-wide and 38.2% statewide. Rocketship Mosaic Elementary outperforms its district average for low-income students by 21.2 percentage points in ELA. Other subgroups: Low-Income students (61.2% Math proficient); Hispanic students (41.6% ELA proficient). The largest proficiency gap is 23.6 percentage points for english learner students. Data source: California Department of Education, CAASPP 2024-25. 167 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

Rocketship Mosaic Elementary: reading the evidence

Rocketship Mosaic posts 57% meeting the standard, and 32.5% 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 whether the low absenteeism and suspension numbers come from what the school does or from the community it serves — both can produce the same numbers, and only a visit tells you which.

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.
