🌱 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 “9% proficient” and call it done. Delta deserves a closer read. The school sits in Santa Maria, where three in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.

The story this school is actually telling
Of 100 students here: 9 are proficient by 11th grade → 92 graduate → 0 pass an AP exam. The gaps between those bars are the questions to ask.
The 7 things our score weighs
Ask what changed in the last two years, and what the school is asking families for. Growth shows up in these numbers a year or two after it shows up in classrooms.
- Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
- 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.
