Summary:
BASIS Charter Schools Inc. has one listed elementary school in Chandler: BASIS Chandler Primary - North Campus, which serves kindergarten through grade 4 and has 619 students. In 2025–26, its all-grades AASA proficiency rates were 89% in English language arts (ELA) and 94% in math, compared with Arizona rates of 41% and 33%. That puts the school 48 percentage points above the state in ELA and 61 points above in math. The most important finding for parents is that the school’s results are far above statewide rates in both subjects, with its largest advantage in math.
BASIS Chandler Primary - North Campus is the only school in this list, so there are no local schools to place above or below it. Its strong state comparisons hold in both tested grades. In grade 3, ELA proficiency was 86% versus 39% statewide, a 47-point advantage, and math was 97% versus 38%, a 59-point advantage. In grade 4, ELA was 91% versus 47%, a 44-point lead, while math was 91% versus 40%, a 51-point lead. The school’s highest reported result was grade 3 math at 97%; its lowest was grade 3 ELA at 86%, still well above the state rate.
SchoolDigger gives the school 5 stars and ranked it 3rd of 900 Arizona schools in 2025–26; its overall ranking was 4th of 912 in 2023–24 and 3rd of 909 in 2024–25. Those rankings show a consistently high position in SchoolDigger’s system, but they do not show whether test scores are rising or falling. The school’s reported student-teacher ratio was 14.7 in 2024–25, and its free/reduced-lunch percentage is not reported. Because the list contains only this school and AASA proficiency results for only 2025–26, it offers no peer comparison or test-score trend.
