Summary
Iliahi Elementary School is a PK–5 school serving 313 students in Wahiawa, on Oahu’s central plateau, within the single statewide Hawaii Department of Education. Its ten-year rank history shows a recent slide: after reaching the 86th percentile in 2022–23, it fell to the 64th percentile in 2025–26, its lowest mark in the decade shown and its first 3-star rating since 2020–21. In 2025–26, 58% of students were proficient in ELA, 56% in math, and 50% in science; chronic absenteeism was 21.0%, improved from 26.2% but still high, and the student–teacher ratio was 13.0:1.
For parents comparing nearby schools, Iliahi Elementary School is the highest-ranked school in Wahiawa proper, edging Wahiawa Elementary School (64 vs. 63 percentile) and well ahead of Kaala Elementary School (41). It trails some schools with similar or greater poverty, though: Helemano Elementary School serves a poorer population (59.2% free/reduced lunch vs. 53.0%) yet outperforms this school in ELA (64 vs. 58), math (60 vs. 56), and science (70 vs. 50), and Kipapa Elementary School also does better across subjects. The Mililani-area schools rank much higher, but they serve far lower poverty rates, so those comparisons are not apples-to-apples. Science is the school’s widest gap, and its absenteeism rate is tied for second-highest among the 11 schools.
The recent decline is broad, but math is steepest: math proficiency fell from 72% in 2022–23 to 56% in 2025–26, while science has consistently been the lowest subject and now sits at 50%. One bright spot: low-income students ranked in the 74th percentile, above the school overall at 64th percentile, suggesting the school supports disadvantaged students well. Special education results have been volatile, and English language learners ranked in the 65th percentile, above the school’s overall standing. The bottom line: Iliahi Elementary School is a historically strong high-poverty school that has lost ground recently, not a low-performing one in absolute terms. Its 13.0:1 ratio and above-average per-student spending (though data is from 2018–19) suggest the infrastructure is in place, with science, math, and absenteeism the clearest areas to watch.
