BASIS Charter Schools Inc.

BASIS Oro Valley Primary is the only school listed in BASIS Charter Schools Inc., serving grades K–6 in Oro Valley, Arizona, with 599 students. Its available 2025–26 results are well above Arizona’s in both reported subjects: 76% met the ELA standard compared with 41% statewide, and 83% met the math standard compared with 33%. The clearest overall takeaway is that the school substantially outperformed the state in both ELA and mathematics.

There is no other school in this group to rank against it, so the school is both the group’s top and bottom performer; the state is the useful benchmark. Its largest all-grades advantage was in math, at 50 percentage points, compared with 35 points in ELA. Within the reported grades, math reached 88% in both fourth and fifth grade, while ELA peaked at 83% in fourth grade and was lowest at 68% in fifth grade. That fifth-grade ELA result was still 30 points above the state’s 38%, but it was 20 points below the school’s fifth-grade math result. Fifth-grade science was also strong at 78%, versus 34% statewide, though that result is from 2024–25 rather than 2025–26.

SchoolDigger ranks the school 24th of 900 Arizona schools for 2025–26, in the 97th percentile, with five stars; its rank was 15th of 912 in 2023–24 and 13th of 909 in 2024–25. The recent ranking slipped by nine places from 2023–24, but that does not show that test performance declined: the available results do not provide a same-grade, same-subject trend across years. The student–teacher ratio is 18.7, based on 2024–25 data, and the free/reduced-lunch rate is not reported. Because this list contains only one school, it cannot support comparisons among schools in the group.
