Riverside Preparatory scores 31 of 100 on SchoolScope's Scope Score — the 20th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Most rating sites would stop at “22% proficient” and call it done. Riverside Preparatory deserves a closer read. The school sits in Oro Grande, where three in four 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, Riverside Preparatory enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions

Is Riverside Preparatory a good elementary school?
Riverside Preparatory has a Scope Score of 31 out of 100, placing it in the 20th percentile of California elementary schools and ranked #4,601 statewide. 6.9% of students exceeded the state standard on the 2025 CAASPP assessment, which is 14.4 percentage points below the California average of 21.3%. 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 Riverside Preparatory's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 22.1% of students at Riverside Preparatory met or exceeded the state standard in ELA and Math combined, and 6.9% exceeded it. The gap between those numbers matters: 15.2% of students are at the proficiency floor, while 6.9% 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. 833 student-subject combinations were assessed.
How does Riverside Preparatory rank in California?
Riverside Preparatory ranks #4,601 among California elementary schools by Scope Score, placing it in the 20th 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 Riverside Preparatory getting better or worse?
Based on 2025 CAASPP data, proficiency at Riverside Preparatory increases by 3.1 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 Riverside Preparatory?
17.2% of students at Riverside Preparatory are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 6.0%. 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 Riverside Preparatory compare to other schools in Oro Grande?
Riverside Preparatory scores 31/100 (20th percentile) among California elementary schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 2,453 students. Use the schools in Oro Grande page or the map view to compare all elementary schools nearby.
How does Riverside Preparatory serve low-income and underrepresented students?
At Riverside Preparatory in Oro Grande, 32.0% of low-income students met or exceeded the ELA standard in 2025, compared to 23.1% district-wide and 38.2% statewide.

Data source: California Department of Education, CAASPP 2024-25. 1,063 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
