Lorbeer Middle: The state doesn't publish enough data to score this school fairly.
Lorbeer is a middle school in Diamond Bar. The state doesn't publish enough data to score it fairly — so we won't. Here's what we can show.
No Scope Score available
California doesn't publicly report per-grade test results when fewer than 11 students are tested in a grade — a privacy protection for small schools. We can't compute a Scope Score without that data.
With little published data, 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.

What gets spent here
These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.
$393 per student arrives as federal Title funding — a measure of concentrated need, not school quality.
The district's current expense of education per student, from CDE's annual SACS filing — the freshest district spending figure the state publishes.
District-level, from the district's own SACS general-ledger filing — school-by-school breakdowns aren't published by the state.
