ISANA Achernar Academy scores 27 of 100 on SchoolScope's Scope Score — the 17th 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 →
Most rating sites would stop at “15% proficient” and call it done. ISANA Achernar Academy deserves a closer read. The school sits in Compton, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.
As a charter, ISANA Achernar Academy enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions
Is ISANA Achernar Academy a good elementary school?

The Scope Score weights six dimensions for elementary schools: exceeded standard (43%), met or exceeded (22%), grade 3-to-5 growth (15%), chronic absenteeism (10%), ELPAC English Learner proficiency (5%), and suspension rate (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are ISANA Achernar Academy's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 15.0% of students at ISANA Achernar Academy met or exceeded the state standard in ELA and Math combined, and 3.1% exceeded it. The gap between those numbers matters: 11.9% of students are at the proficiency floor, while 3.1% 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. 244 student-subject combinations were assessed.
How does ISANA Achernar Academy rank in California?
ISANA Achernar Academy ranks #4,753 among California elementary schools by Scope Score, placing it in the 17th 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 ISANA Achernar Academy getting better or worse?
Based on 2025 CAASPP data, proficiency at ISANA Achernar Academy increases by 21.6 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 ISANA Achernar Academy?

The suspension rate is 1.4%, 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 ISANA Achernar Academy compare to other schools in Compton?
