Obsidian Middle: The state doesn't publish enough data to score this school fairly.
Obsidian is a middle school in Clearlake. 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.
