California’s growth results and student groups
State growth model · CDE growth model 2024–25
California's own growth model places it near the 18th percentile of 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 well below the middle of California elementary 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 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.

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.

Casterlin Elementary: reading the evidence
Casterlin is a school in Blocksburg. 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.
