💪 Strong All-Around — Ask about what we don't score — class size, electives, the feel of a classroom — strong numbers everywhere on paper don't mean every classroom feels the same.
Most rating sites would stop at “61% proficient” and call it done. San Dimas 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.
San Dimas's low-income kids hit 70.8% 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.

San Dimas's most underrated number
70.8% 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 7 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.
