Flandreau Indian Boarding School

Located at 1132 N Crescent Street in Flandreau, South Dakota, the Flandreau Indian Boarding School operates as an active, standalone public high school district dedicated exclusively to secondary education. Nestled in a rural remote setting, this single-campus district serves students in grades 9 through 12, offering a close-knit academic environment tailored to its distinct student population. Currently, the district enrolls 149 students—comprising 79 female and 70 male learners—all of whom identify as American Indian. The student body is distributed across the upper grades, with 40 freshmen, 54 sophomores, 33 juniors, and 22 graduating seniors forming a vibrant high school community.

To support its academic and specialized residential mission, the district maintains an exceptional staffing infrastructure designed for holistic student support. Classroom instruction is led by 20 full-time equivalent teachers, resulting in a remarkably low student-to-teacher ratio of approximately 7.5 to 1 that enables personalized guidance and mentoring. In addition to teaching faculty, the district employs 3 instructional aides and a substantial team of nearly 72 support staff members, bringing the total district workforce to roughly 95 full-time equivalent personnel. This high ratio of specialized support staff underscores the district’s commitment to wraparound services, cultural responsiveness, and individual development for every student on campus.
