CDE CAASPP 2025

Most rating sites would stop at “62% proficient” and call it done. Chaffey District Online deserves a closer read. The school sits in Ontario, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 42.6% of students scored in the top band on the state test. The California average is 15.8%.

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

Ask what share of students complete the full college-prep course sequence, and who gets steered into it.
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.
