Most rating sites would stop at “54% proficient” and call it done. River Islands Technology Academy II deserves a closer read. The school sits in Lathrop, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 51.8% of low-income students met the ELA standard — versus 38.2% for the same group statewide.

As a charter, River Islands Technology Academy II enrolls by application, not address — the score reads the same, the enrollment path doesn't.

What are River Islands Technology Academy II's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 53.6% of students at River Islands Technology Academy II met or exceeded the state standard in ELA and Math combined, and 28.8% exceeded it. The gap between those numbers matters: 24.9% of students are at the proficiency floor, while 28.8% pushed past it. Most rating sites report only the combined "proficient" number.

How does River Islands Technology Academy II rank in California?
River Islands Technology Academy II ranks #1,732 among California elementary schools by Scope Score, placing it in the 70th 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 River Islands Technology Academy II getting better or worse?
Based on 2025 CAASPP data, proficiency at River Islands Technology Academy II decreases by 22.2 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.

SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
