🌱 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 “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%.
The seven-year arc
Climbed from the 47th to the 76th percentile since 2019 — past roughly 600 high schools.
The pandemic drop is behind this school: 62% of students meet the standard today, above the 52% who did in 2019.

The story this school is actually telling
Of 100 students here: 62 are proficient by 11th grade → 94 graduate → 5 pass an AP exam. The gaps between those bars are the questions to ask.
The 6 things our score weighs
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.

Class of 2023: 21 completers, 76% enrolled somewhere within a year
Percentages are computed by SchoolScope (count ÷ completers) from CDE-reported counts, not a CDE-native rate.
Data source: California Department of Education, 2023 cohort — the newest published; National Student Clearinghouse match.
UC is one road of many — the full destination mix for the class of 2023 is below. And who applied isn't who the school taught: the ratio between the two reflects the self-selected pool of students who chose to apply, not what happened in the classroom. By the state's 2023 count, 76% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (12) than at UC (1).
