Alameda Science and Technology Institute: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.

Alameda Science and Technology Institute posts 46.0% exceeding the standard — versus 15.8% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.

ranked #263 statewide · #3 of 5 in Alameda Unified

Alameda Science and Technology Institute scores 62 of 100 on SchoolScope's Scope Score — the 88th percentile of 2,160 California high schools (CDE CAASPP 2025).

CDE CAASPP 2025

Most rating sites would stop at “84% proficient” and call it done. Alameda Science and Technology Institute deserves a closer read. The school sits in Alameda, where two in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Alameda Science and Technology Institute's low-income kids hit 95.5% 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 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.
