Academically, South Mountain High School consistently ranks in the bottom quartile of Arizona high schools, with only 6% of 11th-grade students proficient or better in Science, compared to 19% statewide and 9% in the district. The school's English Language Arts and Mathematics proficiency rates for 11th-grade students are also well below the state and district averages, ranging from 12-16% and 7-8% respectively, compared to 38-40% and 30% statewide. Additionally, the school's four-year graduation rate has ranged from 75.2% to 79.6% over the past few years, lower than the state and district averages, and its dropout rate has been consistently higher.

While South Mountain High School faces significant challenges, the presence of several nearby charter schools, such as ASU Preparatory Academy - Phoenix High School and AAEC - SMCC Campus, which have outperformed the school on various academic metrics, may present opportunities for collaboration and learning from best practices. Addressing the school's low performance and high dropout rates will require a comprehensive, data-driven approach that focuses on improving instructional quality, supporting student engagement and well-being, and leveraging community partnerships to provide additional resources and opportunities for the school's diverse student population.
