Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
🤝 Culture First — 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.
Most rating sites would stop at “30% proficient” and call it done. Twin Ridges Home Study Charter deserves a closer read. The school sits in Nevada City, where two in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.
As a charter, Twin Ridges Home Study Charter enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

The 5 things our score weighs
Ask what changed in the last two years, and what the school is asking families for. Growth shows up in these numbers a year or two after it shows up in classrooms.
- Ask what changes between grade 3 and grade 5 here, and who teaches the older kids.
- 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.

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.
$189 per student arrives as federal Title funding — a measure of concentrated need, not school quality.
