Summary:
The 85253 high-school list contains one school, Chaparral High School, which serves grades 9–12 in Scottsdale Unified District. In 2025–26, Chaparral’s all-grades proficiency was 67% in English language arts (ELA) and 59% in math, compared with Arizona rates of 41% and 33%. Its state advantages were 26 percentage points in each subject. For 11th grade, it was 29 points above the state in ELA and 28 points above in math. The most important finding is that Chaparral’s ELA and math results are substantially above Arizona’s, both schoolwide and in 11th grade.
Chaparral is the only listed school, so there is no local top-to-bottom comparison; its strongest results are in ELA and math, while science is a notable exception. Although its all-grades ELA proficiency of 67% is higher than its 59% in math, its advantage over the state is the same in both subjects. In 11th-grade science, Chaparral reached 19% in 2024–25, matching Arizona and falling 3 points below the district’s 22%. The subject results therefore show a clear state-relative strength in ELA and math, but not in science.
SchoolDigger’s ranking shows a stronger relative position in its latest listing: Chaparral moved from 64th of 271 schools (76th percentile) in 2024–25 to 33rd of 256 (87th percentile) in 2025–26, an improvement of 31 places and 11 percentile points; its 2023–24 listing was 55th of 270 (80th percentile). This ranking change does not establish that test scores rose, since comparable results across multiple years are not provided. The school’s student-teacher ratio was 21.3 in 2024–25, and no free/reduced-lunch rate is reported. Its graduation rate was 97% in 2023–24; the district and state figures were 94% and 80% in 2024–25. Because this is a one-school list and the graduation and dropout figures come from different years, it cannot show local school-to-school patterns or provide same-year comparisons with the benchmarks.
