🌱 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 “46% proficient” and call it done. Allen (Decima M.) deserves a closer read. The school sits in San Bruno, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 22.4% of English learners met the ELA standard — versus 10.4% statewide.

The school, grade by grade
ELA · CAASPP 2024–25Different students, same year — each bar is one grade's proficiency mix.
The honest read: the share exceeding falls 5.2pp across grades; the floor slips 8.9pp. The state average rises 4.5pp over the same span. The school's 5th graders aren't posting a wider lead than its 3rd graders. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.
The 6 things our score weighs
Ask the principal what changes between grade 3 and grade 5. Ask who teaches the older grades, and what the school does when a child starts falling behind.
- Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
- Ask what changes between grade 3 and grade 5 here, and who teaches the older kids.
- 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.
