Summary:
Zip code 92618 has six Irvine Unified schools serving 5,679 students: three serve kindergarten through grade 8 and three serve kindergarten through grade 6. In 2025–2026, every school scored above state rates in all-grades English language arts (ELA), math and science. But those strong area-wide results hide a substantial gap: Oak Creek Elementary is the clear outlier, with the lowest proficiency in all three subjects and scores much closer to state rates than those of its local peers.
Beacon Park leads ELA at 78%, about 2 percentage points ahead of Portola Springs Elementary and 7 points above the six-school average. Those two schools are essentially tied for the top in math at about 74%. Loma Ridge Elementary leads science at 70.3%, just above Beacon Park at 69.7%. Oak Creek’s rates are 59% in ELA, 52% in math and 46% in science—12, 15 and 17 points below the respective school averages. Its fourth-grade math rate, 43%, is also barely above the state’s 42%.
Recent results are mixed: from 2024–2025 to 2025–2026, the school averages fell by about 1 point each in ELA and math, while science rose 5 points, with the largest science gains at Portola Springs and Loma Ridge. SchoolDigger rankings worsened over the three-year period for Beacon Park, Portola Springs, Oak Creek and Solis Park; Oak Creek fell 298 places, while Loma Ridge and Cadence Park improved. Context differs too: in 2024–2025, free/reduced lunch eligible rates ranged from 12% at Loma Ridge to 29% at Oak Creek. Portola Springs and Oak Creek had similar student-teacher ratios (30.1 and 30.0), despite their different results. Oak Creek’s chronic absenteeism was 19%, versus about 7%–8% at the other schools.
