Mary Ellen Halvorson Educational Foundation. dba: (10965)

Located at 5522 Side Road in Prescott, Arizona, the Mary Ellen Halvorson Educational Foundation operates as an active, independent public charter district doing business as Tri-City Prep. Set within a rural fringe environment in the Prescott Valley metropolitan area, this single-school district is authorized to serve students across grades 5 through 12, providing a continuous academic pathway from late elementary through high school graduation. As an open public charter entity responsible for its own regional and federal educational programs, the district offers a focused, community-oriented learning alternative designed to foster academic growth in a personalized setting.

In the 2024–2025 school year, the district maintains a close-knit enrollment of 278 students, with primary concentration across middle and high school grade levels. The student population represents a diverse mix of backgrounds—including 208 White, 52 Hispanic, 8 multiracial, 4 Asian, 4 Black, and 2 American Indian students—comprising 133 female and 145 male learners. A defining feature of the district's operational context is its robust instructional staffing, which includes nearly 42 full-time equivalent teachers. This exceptional educator presence yields a remarkably low student-to-teacher ratio of roughly seven to one, ensuring that students receive individualized attention, strong mentorship, and an engaging learning environment tailored to post-secondary preparation.
