Summary:

ZIP code 85021 has 14 schools: three elementary schools, one middle school, nine high schools and one alternative school, along with a mix of traditional and online options. Their reported academic results vary widely, so families will find notably different outcomes across schools. The clearest overall contrast is between Sunnyslope High School at the top of reported all-grades results and Richard E. Miller School at the bottom.

Sunnyslope recorded 56% proficiency in ELA and 48% in math in 2025–26; Miller had 20% and 18%, leaving gaps of 36 and 30 percentage points. Sunnyslope was also 15 points above the state rate in both subjects, while Miller was 21 points below in ELA and 15 below in math. A strong grade-level result at Orangewood School is easy to miss in its overall figures: seventh graders reached 53% in ELA and 45% in math, respectively 10 and 18 points above state rates and 21 points ahead of Royal Palm Middle School in each subject. Graduation rates were also high at Sunnyslope and Washington High School: 94% and 93%, compared with 80% statewide.

SchoolDigger statewide percentiles improved for four of the five schools with three-year histories: Sunnyslope rose from the 66th to the 77th percentile, Washington from the 38th to the 51st, Royal Palm from the 35th to the 42nd, and Miller from the 4th to the 6th; Orangewood fell from the 27th to the 17th. The five-school average rose from 34 to 39, a five-point gain, but that average masks Orangewood’s decline and stronger high-school gains. Size and student-teacher ratio do not provide a simple guide to results: Sunnyslope enrolls 2,322 students and has a ratio of 23.7, while Miller’s ratio is 16.8 despite its lower scores. Because schools serve different grades and some small schools have suppressed or unavailable test results, these comparisons are not all like for like.
