Memberships & Affiliations

The Prairie School is proud to partner with local and national organizations that support education at all levels. The organizations below serve our students, families, board members and faculty through professional development opportunities, scholarships, accessibility to educational resources and more!

Accreditation is important because it holds schools to rigorous standards in every area of school life. The accreditation process engages the entire school community, bringing it together to affirm its mission, identify areas of strength and weakness, and articulate plans for improvement. The accreditation process culminates with an extensive examination of each school by a visiting team of experts every seven years. Accreditation is a helpful indicator of quality.

The Prairie School is accredited by the following two organizations:


Advanced Ed insists on a relentless pursuit of excellence – for itself and for the institutions it accredits. Their comprehensive process aligns accreditation with accountability, emphasizing learner outcomes when evaluating institutional quality. Advanced Ed collaborates with over 32,000 schools and school systems—employing more than four million educators and enrolling more than 20 million students—across the United States and 70 other nations.
