Vista Oaks Charter: Kids show up — absenteeism runs far below the state. But math slips between grade 3 and grade 5.

Vista Oaks Charter has real strengths and one number that complicates them. Most rating sites show you one or the other. Both belong on the same page.

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

Most rating sites would stop at “43% proficient” and call it done. Vista Oaks Charter deserves a closer read. The school sits in Lodi, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 4.5% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.

As a charter, Vista Oaks Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.

The honest read: the share exceeding falls 5.0pp across grades; the proficiency floor barely moves. The state average rises 4.5pp over the same span. The school's 5th graders aren't posting a wider lead than its 3rd graders. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.

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 Vista Oaks Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 43.1% of students at Vista Oaks Charter met or exceeded the state standard in ELA and Math combined, and 19.6% exceeded it. The gap between those numbers matters: 23.5% of students are at the proficiency floor, while 19.6% 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. 464 student-subject combinations were assessed.
How does Vista Oaks Charter rank in California?
Vista Oaks Charter ranks #2,499 among California elementary schools by Scope Score, placing it in the 56th 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 Vista Oaks Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Vista Oaks Charter decreases by 6.4 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 Vista Oaks Charter?

The suspension rate is 0.1%, 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 Vista Oaks Charter compare to other schools in Lodi?
