Robert Heideman Elementary scores 39 of 100 on SchoolScope's Scope Score — the 41st percentile of 5,744 California elementary schools (CDE CAASPP 2025).

🌱 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 “29% proficient” and call it done. Robert Heideman deserves a closer read. The school sits in Tustin, where nearly all students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

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 changes between grade 3 and grade 5 here, and who teaches the older kids.
  • 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.

Worth Knowing

Transitional kindergarten is offered here — confirmed by actual Census Day enrollment, not just the listed grade span.

On the state's science test (CAST), 7% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

Is Robert Heideman Elementary getting better or worse?

Growth trajectory is weighted at 15% in the elementary Scope Score because it measures what the school does, not just who walks in the door.
