BASIS Charter Schools Inc.

The BASIS Charter Schools Inc. list contains one school, BASIS Phoenix North, a K–8 campus with 152 students; the supplied grade-level results cover grades 3–6. The most important finding is that the school is well above state proficiency levels in every reported measure: 73% versus 41% in all-grades ELA and 72% versus 33% in all-grades math in 2025–2026, plus 82% versus 34% in fifth-grade science in 2024–2025.

With just one school, there is no top-versus-bottom comparison among campuses; BASIS Phoenix North is the only school in the list and stands out against the state in all three measures. SchoolDigger ranks it 69th out of 900 schools, at the 92nd percentile, and gives it five stars; SchoolDigger ranks the district 22nd out of 267. Within the school, results vary by grade: ELA is highest in grade 4 at 83% and lowest in grade 6 at 59%, a 24-point spread. Math peaks at 85% in grade 3 and is lowest at 54% in grade 6, a 31-point spread. Even in grade 6, results remain above the state: 59% versus 41% in ELA and 54% versus 30% in math.

The grade-level pattern is less even in the upper tested grades, especially in math, but it does not show whether results are improving or declining over time: the supplied data include just one year of AASA results. ELA falls from 81% in grade 3 and 83% in grade 4 to 60% in grade 5 and 59% in grade 6; math declines from 85% in grade 3 to 54% in grade 6. The reported student–teacher ratio is 11.6, while the free/reduced-lunch figure is not provided. Since this list has only one school, it cannot show how achievement compares across nearby schools or how results relate to school characteristics.
