Summary:
The area served by Glendale Preparatory Academy has one listed school: Great Hearts Academies - Glendale Prep, a grades 6–12 school with 657 students and a reported student–teacher ratio of 12:1. Its 2025–26 results put it well above Arizona statewide proficiency in both main tested subjects: ELA was 65% versus 41% statewide, and math was 60% versus 33%. The most important finding is that the school’s advantage over the state is substantial in both subjects, and larger in math.
Grade 11 is the school’s strongest standout, while some lower-grade results are more modest. In grade 11, ELA proficiency was 91% compared with 38% statewide, and math was 78% compared with 31%—advantages of 53 and 47 percentage points. Across grades 6, 7, 8 and 11, ELA ranged from 53% in grade 8 to 91% in grade 11; math ranged from 53% in grade 6 to 78% in grade 11. The school was also above the state in both reported AzSCI grades: grade 8 science was 62% versus 30%, and grade 11 was 65% versus 19%. These differences show why it is useful to look beyond the all-grades figures: results vary by grade, even though each reported comparison favors the school.
SchoolDigger’s statewide ranking improved across the three years shown, from 12th of 270 schools in 2023–24 to 9th of 271 in 2024–25 and 5th of 256 in 2025–26; its listed percentile also rose from 96 to 98. This is a favorable ranking trend, but the available AASA results cover only 2025–26, so they do not establish a change in test scores over time. The reported 12:1 student–teacher ratio offers additional context, while no free/reduced-lunch rate is provided. Because only one school is listed, there is no school-to-school comparison to help families weigh alternatives.
