Most rating sites would stop at “70% proficient” and call it done. Sixth Street Prep deserves a closer read. The school sits in Victorville, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Sixth Street Prep's low-income kids hit 76.9% 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.
As a charter, Sixth Street Prep enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

The 5 things our score weighs
Ask what changed — new curriculum, new principal, new program. Momentum has a cause, and a visit will find it.
- Ask how teachers track each child's growth over the year, not just where the class lands on test day.
- 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.
