Foster Elementary scores 37 of 100 on SchoolScope's Scope Score — the 34th 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 “37% proficient” and call it done. Foster deserves a closer read. The school sits in San Diego, where more than half of 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 how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
  • 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), 22% met or exceeded the standard — science is tested in grades 5 and 8 but never enters the Scope Score.

Frequently asked questions

Is Foster Elementary a good elementary school?

Foster Elementary has a Scope Score of 37 out of 100, placing it in the 34th percentile of California elementary schools and ranked #3,798 statewide. 17.6% of students exceeded the state standard on the 2025 CAASPP assessment, which is 3.8 percentage points below the California average of 21.3%. The Scope Score weights 6 dimensions for elementary schools: exceeded standard (38%), grade 3-to-5 growth (27%), met or exceeded (proficient) (20%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

What are Foster Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 37.3% of students at Foster Elementary met or exceeded the state standard in ELA and Math combined, and 17.6% exceeded it. The gap between those numbers matters: 19.7% of students are at the proficiency floor, while 17.6% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 409 student-subject combinations were assessed.

How does Foster Elementary rank in California?

Foster Elementary ranks #3,798 among California elementary schools by Scope Score, placing it in the 34th 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 Foster Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Foster Elementary decreases by 12.0 percentage points from Grade 3 to grade 5 growth. This downward pattern doesn't necessarily mean the school is failing — it can reflect cohort differences, demographic shifts, or curriculum changes. A campus visit and conversation with teachers can reveal what the numbers can't. 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.

What is the attendance and school culture like at Foster Elementary?

28.1% of students at Foster Elementary are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 1.6%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.

How does Foster Elementary compare to other schools in San Diego?
