Timber Point Elementary scores 48 of 100 on SchoolScope's Scope Score — the 63rd percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

📈 On the Rise — Ask how many years the improvement has held, not just the latest one — one strong cohort and a real turnaround can look identical in a single year of data.

Most rating sites would stop at “44% proficient” and call it done. Timber Point deserves a closer read. The school sits in Discovery Bay, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Worth a school visit

Ask how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.

  • 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.

What are Timber Point Elementary's CAASPP test scores?

How does Timber Point Elementary rank in California?

Timber Point Elementary ranks #2,131 among California elementary schools by Scope Score, placing it in the 63rd percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 growth), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.

Is Timber Point Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Timber Point Elementary increases by 3.1 percentage points from Grade 3 to grade 5 growth.
