Island Elementary scores 56 of 100 on SchoolScope's Scope Score — the 76th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

🚀 Growth Engine — Ask how the school tracks each kid's growth year to year, and what happens when a kid stalls instead of gaining.

Most rating sites would stop at “48% proficient” and call it done. Island deserves a closer read. The school sits in Lemoore, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Island's low-income kids hit 54.8% 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.

As a charter, Island enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

Worth a school visit

Ask what changed — new curriculum, new principal, new program. Momentum has a cause, and a visit will find it.

  • Ask how teachers track each child's growth over the year, not just where the class lands on test day.
  • 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.

Frequently asked questions

Is Island Elementary a good elementary school?

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

What are Island Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 47.6% of students at Island Elementary met or exceeded the state standard in ELA and Math combined, and 19.9% exceeded it. The gap between those numbers matters: 27.7% of students are at the proficiency floor, while 19.9% 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. 284 student-subject combinations were assessed.

How does Island Elementary rank in California?

Island Elementary ranks #1,354 among California elementary schools by Scope Score, placing it in the 76th 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 Island Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Island Elementary increases by 17.5 percentage points from Grade 3 to grade 5 growth. This upward trajectory suggests the school is adding measurable value — students leave with higher proficiency rates than they entered with. 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 Island Elementary?

The suspension rate is 1.5%, 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.
