262^nd

SchoolDigger Rank ?

of 5,804 California Elementary Schools

Better than 95% of California elementary schools

Summary

Oso Grande Elementary serves 867 students in kindergarten through fifth grade in Ladera Ranch, a community in Orange County. In 2025–2026, its proficiency rates were higher than both state and Capistrano Unified averages in English language arts (ELA), math and science. The most important takeaway is that Oso Grande is a strong nearby school, especially in ELA and math, though fifth-grade math stands out as an area to watch.

Oso Grande’s strongest local results are in ELA and math: among nine nearby district elementary schools, it ranks second in both, behind only Chaparral Elementary. Oso Grande’s 2025–2026 proficiency was 82% in ELA, 79% in math and 64% in science—11, 17 and 5 percentage points above district averages, respectively, and 33, 41 and 28 points above state averages. It also exceeded the nearby-school averages by 12 points in ELA, 10 in math and 5 in science; science ranks sixth locally, making it less exceptional than its other subjects. Fifth-grade math was 69%, down 20 points from fourth grade’s 89%, and ranked sixth among the nearby schools, although it remained above district and state rates.

Scores have risen overall since 2022–2023: ELA gained 4 points, math 3 and science 3. Science has fluctuated, however, falling after a 2023–2024 peak before a modest recovery. SchoolDigger ranks Oso Grande 262nd of 5,804 California schools, at the 95th percentile with 5 stars; its percentile has stayed between 92 and 95 across reported years, while Chaparral is higher locally at the 99th percentile. In 2024–2025, Oso Grande had the nearby group’s highest student–teacher ratio, 27.0 to 1, and its free/reduced lunch eligible share was 14%, the lowest in the group. Chronic absenteeism fell from 21% in 2021–2022 to 7% in 2025–2026, below district and state rates.

Sunday, May 3, 2020

Don’t be fooled by standardized test scores, they’re the only focus. If you’re looking for a global and well rounded education that prepares your child for the next phase of life look beyond Oso Grande. If you’re looking for any sense of multicultural education and inclusion, they’re both discouraged as Oso Grande. Seek out a parent that no longer sends their children to Oso Grande to get the truth about the school Close Quote
