Understanding the 3/10 Rating
Tolleson Union High School District has earned an overall SchoolDistrictFinder rating of 3/10, placing it in the below average tier. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in Arizona’s AASA/ACT/MSAA combined assessments (2025 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Arizona is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Tolleson Union High School District carries a below-average rating, with reading and math proficiency rates below typical Arizona benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.
