About Patagonia Union High School District
Zip code 85637 in Patagonia Union, Arizona is served by Patagonia Union High School District for public school enrollment. The district covers grades Pre-K–12th. This page provides a data-driven overview of Patagonia Union High School District’s funding levels, size, rating, and what families should know before enrolling or making a housing decision in this area.
Understanding the 4/10 Rating
With a rating of 4/10 (below average), Patagonia Union High School District ranks among Arizona’s below average-rated school systems. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection (2021–22 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.
⚠️ Small-district caveat. Patagonia Union High School District enrolls 79 students. A percentile rank drawn from so few test-takers is statistically unstable — it can move several points from one year to the next on normal variation alone, and a single class of students can swing it. Treat this rating as a rough signal rather than a precise ranking, and look at the school-level detail below before drawing conclusions.
Patagonia 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.
