Original Research by School Decision on Asu Preparatory Academy - South Phoenix High School
ASU Preparatory Academy – South Phoenix High School is a tuition-free public charter school serving grades seven through twelve in the South Phoenix area. It is one campus in the larger ASU Preparatory Academy network, which has been expanding in recent years with new openings elsewhere in Arizona, though this school operates under its own Local Education Authority. The school is located on South 12th Street in Phoenix, a large and fast-growing city with a broad economy centered on services, technology, manufacturing, tourism, and transportation, anchored by Sky Harbor International Airport. The surrounding housing market has seen home values decline slightly over the past year, and rents have also edged downward. The area is car-oriented with wide, grid-pattern streets, and Phoenix remains one of the fastest-growing cities in the nation.
The school enrolls a small student body across all secondary grades. The largest grade cohort is in tenth grade, and enrollment tapers off only slightly through twelfth grade, suggesting reasonable retention through the high school years. Demographically, the student population is predominantly Hispanic, with small shares of White, Black, and Native American students, and very few Asian or multiracial students. Data on the share of students who qualify for free or reduced-price meals, receive special education services, or are classified as English learners was not available. A parent may want to follow up with the school directly for that information.
State testing data for the most recent school year was largely suppressed for all three tested subjects and grade levels, which often happens when the number of students in a given group is too small to report publicly. However, the multi-year trend data that was available shows that for the single year with a reported figure, overall ELA proficiency stood at a rate that was well below the midpoint among districts in Maricopa County, and math proficiency was even lower. The school did not have a reported graduation rate, which is a notable gap for a school serving grades seven through twelve; this may reflect a data suppression issue or another reporting limitation, and a family considering this school should ask about four-year and five-year graduation outcomes directly.
The school is part of a network that emphasizes personalized, project-based learning, and it is chartered by Arizona State University, which gives it a direct university affiliation. The district brief notes that this is a single-school charter district, meaning it does not have bonding authority or property tax referendums like a traditional school district would. The broader ASU Prep network has opened multiple new campuses in recent years in other Arizona communities, signaling organizational growth and investment, though those campuses are in separate LEAs and do not directly affect this school.
For a family weighing this option, the most important unknowns are the academic proficiency picture, which is difficult to read due to suppressed data, and the missing graduation rate. The school’s small size and university-connected model may appeal to families looking for a personalized approach and a direct pipeline to higher education, but the available evidence does not provide a clear picture of academic outcomes. A prospective parent should ask the school for its most recent test results, graduation rates, college enrollment data, and information on special education and English learner supports before making a decision.
