Summary

Copper Basin is an elementary school (grades PK-8) located in San Tan Valley, Arizona, with 558 students enrolled. The school is part of the Florence Unified School District, which is ranked 248 out of 289 districts in the state and has a 1-star rating from SchoolDigger.

Copper Basin consistently performs below the district and state averages on standardized tests across all grade levels and subjects. For example, in 2024-2025, only 18-33% of Copper Basin students were proficient in English Language Arts, compared to 23-46% for the district and 36-46% for the state. In mathematics, Copper Basin's proficiency rates ranged from 21-22%, while the district was at 19-28% and the state was at 29-42%. Copper Basin has been ranked in the bottom 25% of Arizona elementary schools for the past several years, with a 1-star rating from SchoolDigger for most of that time. The school's performance is particularly low for certain student subgroups, such as female students, male students, Hispanic students, and special education students.

Interestingly, Copper Basin's performance is significantly lower than most of the nearby schools, including Legacy Traditional-San Tan and Eduprize School, both public charter schools that consistently outperform Copper Basin and the district on academic measures. Despite the school's low performance, its per-student spending has increased in recent years, suggesting that funding may not be the primary driver of the school's underperformance. The combination of low academic performance, high dropout rates, and a high percentage of students from low-socioeconomic backgrounds suggests that Copper Basin may be facing complex challenges related to student engagement, family support, and access to resources.
