Summary:
The Excalibur Charter Schools Inc. area has one school, Avalon Elementary, serving kindergarten through grade 8; it has 313 students and a student–teacher ratio of 14.9. In 2025–2026, Avalon was below Arizona in both all-grade subjects, with its largest shortfall in math: 15% proficient, 18 percentage points below the state’s 33%.
Because Avalon is the only school in the area, it is the sole option rather than a local top-or-bottom comparison. Its strongest reported grade-level result was sixth-grade ELA, where it matched Arizona at 41%. Grade 5 ELA was 35% versus 38% statewide, while grade 4 ELA was 32% versus 47%, a 15-point gap. Grade 4 math was also below the state, at 28% compared with 40%. Overall, ELA was closer to the state result than math: 30% versus 41%, an 11-point gap, compared with math’s 18-point gap.
SchoolDigger’s ranking for Avalon improved over the three reported years: it moved from 649 of 912 schools, at the 29th percentile, in 2023–2024 to 593 of 900, at the 34th percentile with 2 stars, in 2025–2026. That is 56 rank positions higher and a 5-point increase in percentile, but it does not establish that test scores improved. Some grade-level scores are suppressed, earlier AASA results and a free/reduced-lunch rate are not supplied, and there are no peer schools for comparison, so the available information cannot establish a proficiency trend or explain results through staffing or income context.
