Summary

Sunnyslope High School is a Phoenix public school serving grades 9–12, with 2,322 students, in the Glendale Union High School District. SchoolDigger gives it 4 stars and ranks it 58th of 256 Arizona schools, at the 77th percentile for 2025–2026; the district earns 2 stars and is at the 46th percentile. The most important finding for families is that Sunnyslope’s ELA and math proficiency rates are well above both state and district levels.

Sunnyslope is especially strong in ELA and math compared with nearby schools that report scores. In 2025–2026, 56% of students were proficient in ELA, versus 40% districtwide and 41% statewide; the rates were 37% at Washington High School and 23% at Cortez High School. Math proficiency was 48%, compared with 32% in the district, 33% statewide, 34% at Washington and 22% at Cortez. Science is a relative weak spot: grade 11 proficiency was 23% in 2024–2025, still above the district’s 17%, state’s 19%, Washington’s 13% and Cortez’s 11%. Graduation is another strength: Sunnyslope’s 94% rate was 7 points above the district, 14 above the state, and 1–2 points above the nearby schools.

Science results have declined from 27% in 2022–2023 to 23% in 2024–2025, while SchoolDigger’s overall percentile ranking rose from 66 to 77 over the same recent three-year period, moving from 3 stars to 4. SchoolDigger’s subgroup rankings show a notable contrast: the school ranks at the 95th percentile for Multi-racial Students, compared with its overall 77th percentile, and at the 61st percentile for Low Socio Economic Status Students, 16 points below its overall ranking. Sunnyslope’s student-teacher ratio was 23.7 in 2024–2025, above Washington’s 22.1 and Cortez’s 21.6; its reported free/reduced-lunch rate was 41% in 2022–2023, with no comparable nearby rates reported.

Open Quote Students park where ever they choose in near by neighborhoods and school doesn't care Close Quote

Open Quote Teachers seem to care, academics are challenging enough, and the community of parents is wonderful. However, the school atmosphere is greatly affected by assistant principals on power trips who seem to enjoy humiliating kids and by football coaches who are verbally abusive bullies. How does a school fight bullying when those in charge are the worst offenders? Sunnyslope needs to keep its leaders in check. Close Quote

Open Quote I've sent 3 children to Sunnyslope (on variance out of Paradise Valley), best decision ever. Glendale Union is very well organized and knows how to deliver a quality education to ALL students. It's easy to reach your child's teachers, administrators are approachable. Student involvement is encouraged. Add to that high expectations for students and behavior accountability. Close Quote
