Summary:
Arthur, Illinois, has two schools serving prekindergarten through grade 12: Arthur Grade School (PK–8) and Arthur-Lovington-Atwood-Hammond High School (grades 9–12). Their scores are not a direct school-to-school ranking, but both show strong results in some areas alongside meaningful weaknesses: the grade school’s all-grades ELA was above the state, while the high school’s ELA was above the state in all three tested grades, and both schools had weaker results in particular math or science grades.
The clearest grade-school standout was grade 7: in 2025–2026, ELA proficiency was 81%, 23 points above the state, and math was 61%, 22 points above. The contrast is grade 5 ELA, at 43%, 12 points below the state, and science, which was below the state in both tested grades. At the high school, grade 11 ACT results were above state results in all three subjects: ELA by 10 points, math by 11, and science by 3. Grade 9 was the main weak spot: PreACT math was 15 points below the state and science was 13 points below. The high school also reported a 98% graduation rate, compared with 90% statewide.
Results shifted unevenly over time. Grade-school all-grades ELA rose from 61% in 2024–2025 to 63% in 2025–2026, but its state lead narrowed by 1 point; math fell from 40% to 38%, moving from 1 point above the state to 2 points below. At the high school, grade 10 ELA rose 11 points, while grade 9 science fell 28 points. SchoolDigger’s statewide percentile rose and then fell for the high school (68, 76, 65 across 2023–2024 to 2025–2026), while the grade school’s declined from 70 to 48. As context, in 2024–2025 the grade school had 12.0 students per teacher versus 10.8 at the high school, and 56% versus 47% of students were free/reduced lunch eligible; these figures describe the schools but do not explain their test results.
