CDE CAASPP 2025

Most rating sites would stop at “64% proficient” and call it done. Las Lomas deserves a closer read. It sits at the 93rd percentile of 2,160 California high schools — but the ranking is the least interesting thing on this page.

Las Lomas's low-income kids hit 48.6% 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.

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 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.
