Corona Creek Elementary: Most kids here clear the bar, year after year. The question is what happens after that.

Corona Creek Elementary has a Scope Score of 49 out of 100, placing it in the 66th percentile of California elementary schools and ranked #1,943 statewide. 26.6% of students exceeded the state standard on the 2025 CAASPP assessment, which is 5.3 percentage points above the California average of 21.3%. The Scope Score weights 6 dimensions for elementary schools: exceeded standard (38%), grade 3-to-5 growth (27%), met or exceeded (proficient) (20%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

On the 2025 CAASPP Smarter Balanced Assessment, 59.7% of students at Corona Creek Elementary met or exceeded the state standard in ELA and Math combined, and 26.6% exceeded it. The gap between those numbers matters: 33.1% of students are at the proficiency floor, while 26.6% 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. 360 student-subject combinations were assessed.

Corona Creek Elementary ranks #1,943 among California elementary schools by Scope Score, placing it in the 66th 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.

Based on 2025 CAASPP data, proficiency at Corona Creek Elementary decreases by 1.1 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.

8.7% of students at Corona Creek Elementary are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%.

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