Summary:
Challenger Basic School Inc. has one elementary school, Challenger Basic School, serving grades K–6. With only one school in the area, there is no school-to-school comparison; the clearest takeaway is that Challenger’s 2025–26 proficiency rates were well above Arizona’s in both subjects: 80% in English Language Arts (ELA) versus 41% statewide, and 77% in mathematics versus 33% statewide.
There is no separate school at the top or bottom of this list, but Challenger’s results stand out against the state in every reported grade. Its largest grade-level result was fourth-grade ELA, at 93% compared with 47% statewide, a 46-point advantage. The lowest school rate was sixth-grade mathematics, at 70%; that was still 40 points above the state’s 30%. Across grades 3–6, ELA proficiency ranged from 73% to 93%, while math ranged from 70% to 83%. The school’s all-grades ELA rate was 3 points higher than its math rate, although its advantage over the state was 5 points larger in math. Fifth-grade science was also above the state in 2024–25: 54% versus 34%, a 20-point difference.
SchoolDigger’s rankings place Challenger near the top, though those rankings do not show whether test scores are rising or falling. Its supplied 2025–26 district ranking is 7th of 267, at the 97th percentile with five stars; its historical school ranking moved from the 95th percentile in 2023–24 to the 94th in 2024–25 and the 98th in 2025–26. That is a net increase of 3 percentile points, and the listed rank improved by 27 places, from 49th to 22nd. Challenger enrolls 274 students and has a reported student–teacher ratio of 13:1; no free/reduced-lunch rate is reported. The list contains no other schools for comparison, and the available test results do not establish a trend over time.
