🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.
Most rating sites would stop at “63% proficient” and call it done. Lone Hill deserves a closer read. The school sits in San Dimas, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Lone Hill's low-income kids hit 57.6% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

Climbed from the 73rd to the 88th percentile since 2019 — past roughly 300 middle schools.

Lone Hill's most underrated number
57.6% of low-income students met the ELA standard — versus 38.2% for the same group statewide. That's the strongest kind of signal a school can post: it holds across income lines.
The 6 things our score weighs
Ask how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.
- Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
- 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.
