Irvine Unified

Irvine Unified includes 43 schools: 30 elementary, six middle, six high and one alternative school, serving students from elementary through high school. Across the groups, average 2025–26 proficiency was above the state level in English language arts (ELA), math and science; for example, middle-school averages were 78% in ELA, 72% in math and 69% in science, versus 49%, 38% and 36% statewide. The most important exception is Creekside High, whose ELA and math results were far below state figures.

Santiago Hills Elementary led the supplied all-grades results in ELA at 86% and math at 84%, respectively 36 and 45 percentage points above the state. Turtle Rock Elementary led science at 83%, 47 points above the state. At the other end, Creekside had 16% in ELA and 25% in math—33 points below the state in ELA and 13 points below in math. Among conventional elementary schools, Oak Creek Elementary was lowest in ELA and math, at 59% and 52%; University Park Elementary was lowest in science, at 38%, just above the state.

Recent changes varied sharply by school: University High rose 8 ELA points, 5 math points and 10 science points from the prior year, while Irvine High fell 10, 5 and 7 points in those subjects. Creekside’s SchoolDigger statewide percentile ranking climbed from 14 to 30 over three years, even as its current proficiency remains low; its chronic absenteeism was 84%, compared with 9% districtwide and 18% statewide. Context measures do not line up neatly with results: in 2024–25, Stone Creek Elementary and Woodbury Elementary were both 18% free/reduced lunch eligible, yet Stone Creek scored 7 ELA points, 10 math points and 17 science points higher. Their student-teacher ratios were similar, at 29.7 and 30.5.
