Is it getting better · CAASPP 2019 to 2025
Has stayed near the 13th percentile since 2019.
A missing score is not a judgment, and it is not a claim about what the state published. It means the composite a Scope Score, band and rank are all built from isn't on file for this school this year — the honest move is to say so, and to show whatever results are on file rather than guess at a number.
This school hasn't fully recovered from the pandemic: 8% meet the standard today, versus 28% 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 places it near the 1st percentile of high 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 well below the middle of California high schools in reading and math together. 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 high school lands at −3 in reading, and the middle half of them fall between −13 and +5 — 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.

The state's growth model, by student group
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 high 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 high school (≈1450).
On the state's science test (CAST), 12% 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.

Plan your next step
What should I do next?
Worth a school visit
With no score to read, a visit does the heavy lifting: ask about class sizes, teacher tenure, and where last year's students went next.
- Ask about typical class sizes and the student-teacher ratio.
- Ask how long teachers have stayed at the school.
- Ask where recent graduates or transfers went next.
- Ask whether the tour can step into a working classroom, and watch how a lesson actually runs.
Use the published evidence to prepare questions, then verify fit and access with the school.

Trona High: reading the evidence
Trona is a high school in Trona. We publish no Scope Score, band or rank for it this year — the composite they are all built from isn't on file. Here's what we can show.
Subject proficiency describes tested students, while graduation describes a graduating cohort. These figures are not successive stages followed by the same students.
