Summary
Arboga Elementary serves 746 students in grades K–8 in Olivehurst, California, among a group of nearby schools with different grade spans. Its 2025–26 all-grades results were better than the nearby-school average in English language arts (ELA), mathematics, and science, but below the state in all three. The most important takeaway is that Arboga compares well with many nearby schools, yet its proficiency rates have not reached the state level in any tested subject.
ELA is Arboga’s strongest result relative to nearby schools: 44% were proficient, 10 points above the nearby-school average and second highest among the 11 schools compared; the result was also 10 points above the district and 5 points below the state. In math, Arboga’s 30% was fifth highest locally, above the nearby average of 27% and the district’s 21%, but 8 points below the state’s 38%. Science proficiency was 30%—third highest locally and above the nearby average of 21% and the district’s 22%, but 6 points below the state’s 36%. Results also differ by grade: eighth-grade ELA was 54%, above the state’s 49%, while seventh-grade math was 18%, 20 points below the state. All-grades comparisons are not like-for-like because nearby schools serve different grade spans.
Scores have risen in ELA and science since 2022–23, while math has barely changed: ELA gained 11 points to 44%, science gained 12 points to 30%, and math gained 1 point to 30%. Over that period, ELA and science narrowed their gaps with the state, while math fell further behind. SchoolDigger placed Arboga at the 49th percentile with 2 stars in 2025–26, tied for second among the nearby schools; its student-teacher ratio was 22.1 in 2024–25, compared with a nearby-school average of 23. Arboga reported that 66% of students were free/reduced lunch eligible in 2024–25. SchoolDigger’s subgroup rankings suggest especially strong standing in serving English Language Learner Students, at the 91st percentile in 2023–24, and Special Education Students, at the 74th percentile in 2025–26, compared with overall school percentiles of 47 and 49 in those respective years. Chronic absenteeism also declined by 23 points, to 13% in 2025–26, below the district’s 19% and the state’s 18%.
