Phoenix Union High School District (4286)

Phoenix Union High School District serves 26,753 students across 20 high schools in the Phoenix metropolitan area. As a high-school-only district — the name makes it explicit — every campus focuses exclusively on grades 9-12. With 18 of its 20 schools ranked, the district averages 5.0 out of 10, a midpoint score that reflects genuine spread across a large, diverse portfolio of campuses.

The top performer is Phoenix Union-Wilson College Preparatory at 8.6 out of 10, the highest mark in the district by a wide margin. Betty Fairfax High School follows at 7.5, and Phoenix Coding Academy earns a 6.9. Phoenix Union Bioscience High School rounds out the upper tier at 6.5. These four schools sit meaningfully above the district's 5.0 average, giving academically motivated students distinct, high-performing targets to pursue.

Phoenix Union stands out for its cluster of specialized academies. Phoenix Coding Academy targets students with technology and computer science interests. Bioscience High School centers on life sciences and research. Wilson College Preparatory is built around rigorous college preparation. Bostrom Alternative Center (6.6) extends coverage to students who need non-traditional learning environments. That range of mission-driven campuses means a student's experience varies significantly depending on which school they attend — this is not a district where campus assignment is a minor detail.

The gap between the district's top schools and the lower-ranked campuses makes individual research essential. Wilson's 8.6 and Betty Fairfax's 7.5 sit far above where the district trails off, so campus selection carries real weight. Parents comparing schools within Phoenix Union should evaluate each campus directly rather than treating district membership as a single, uniform signal. The 5.0 average tells you the floor exists — the specialized academies near the top tell you the ceiling is real too.
