Most rating sites would stop at “13% proficient” and call it done. Calla deserves a closer read. The school sits in Manteca, where two-thirds of 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.

Frequently asked questions
Is Calla High a good high school?
Calla High has a Scope Score of 27 out of 100, placing it in the 17th percentile of California high schools and ranked #1,439 statewide. 0.9% of students exceeded the state standard on the 2025 CAASPP assessment, which is 14.6 percentage points below the California average of 15.5%. The Scope Score weights six dimensions for high 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 Calla High's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 13.4% of students at Calla High met or exceeded the state standard in ELA and Math combined, and 0.9% exceeded it. The gap between those numbers matters: 12.5% of students are at the proficiency floor, while 0.9% 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. 114 student-subject combinations were assessed.
How does Calla High rank in California?
Calla High ranks #1,439 among California high 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), 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.
What is the attendance and school culture like at Calla High?
51.7% of students at Calla High are chronically absent (missing 10% or more of school days), compared to the California average of 32.1%. The suspension rate is 4.7%. 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 Calla High compare to other schools in Manteca?

Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
