American Charter Schools Foundation d.b.a. South R (88334)

Operating as an active, independent charter school district in the heart of Phoenix, Arizona, the American Charter Schools Foundation—doing business as South Ridge Prep—serves high school students in grades 9 through 12 on a single campus. Conveniently located at 6150 N. 16th Street (Suite A) within the vibrant Phoenix-Mesa-Chandler metropolitan area, this open public charter district delivers secondary education within a major urban community setting. During the 2024–2025 academic year, the school enrolled 359 students, maintaining a balanced student body of 180 female and 179 male learners distributed across all four high school levels, ranging from 82 freshmen to 106 seniors. The district reflects a diverse student community, primarily serving Hispanic students (316), along with Black (27), White (9), American Indian (4), and multiracial (3) youth.

To foster student success and personalized learning, the district maintains an exceptionally favorable staffing ratio. Supported by a total workforce of 44 full-time equivalent (FTE) staff members, the district employs 36 FTE classroom teachers alongside 2 instructional aides and 6 dedicated administrative and support personnel. This robust instructional context creates a low student-to-teacher ratio of approximately 10 to 1, allowing educators to offer tailored academic guidance and focused support as students transition toward graduation and post-secondary pathways. For prospective families evaluating high school options and researchers studying single-site urban charter models in Arizona, South Ridge Prep stands out as a focused, community-anchored educational setting.
