Summary:
Scottsdale Preparatory Academy has one listed school, Great Hearts Academies - Scottsdale Prep, serving grades 5–12 with 898 students and a 12.3 student–teacher ratio in 2024–25. Its reported results cover selected grades, not the entire grade span. The most important finding is that the school’s 2025–26 all-grades proficiency rates were well above Arizona’s: 70% in ELA versus 41% statewide, and 56% in math versus 33%.
Scottsdale Prep is both the highest- and lowest-performing school in this list by default, because no other school is included; a meaningful school-to-school comparison is not possible. Its advantage over the state appears across every reported AASA grade and subject, ranging from 18 to 57 percentage points. Grade 11 stands out most: ELA proficiency was 95% versus 38% statewide, and math was 88% versus 31%. In grades 6–8, the advantages were smaller but still substantial, at 18–31 points in ELA and 21–24 points in math. The science results also favored the school, though the gap varied sharply: 9 points above the state in grade 8 and 41 points above in grade 11.
SchoolDigger’s latest ranking places Scottsdale Prep third of 256 schools, in the 99th percentile with five stars; its earlier ranks were eighth of 270 in 2023–24 and eighth of 271 in 2024–25. That history shows a stronger relative ranking in the latest year, but does not establish how test proficiency changed over time. The school’s all-grades advantage was 6 points larger in ELA than in math, while its science advantage was much larger in grade 11 than grade 8. Its free/reduced-lunch figure is blank, so there is no reported income measure to compare.
