Our District The Superior Unified School District #15 is the proud home of exceptional teaching and learning. Located in Pinal County in southeastern Arizona, Superior’s schools provide a safe and supportive environment where children receive quality, rigorous instruction to prepare them for college and careers. The students in SUSD’s three schools enjoy small class sizes and rigorous, challenging curriculum. Both our elementary and junior/senior high schools offer quality programs including athletics, fine arts, various clubs and enrichment activities. We build student character as we educate our students academically, emotionally, and socially. Our goal is to graduate young adults who are ready to take on the world—whether it’s in college or the workforce. We are proud of the opportunities we offer and know that you will be impressed with all we have to offer.
