Accreditation
Minnehaha Academy has been accredited by NCA (North Central Association) since 1964. Recently, the school joined NAIS (National Association of Independent Schools) and a corresponding regional organization, ISACS (Independent School Association of the Central States).

As part of the NAIS and ISACS accreditation process, the school is now engaged in a 3-year self-study, which includes reaffirmation of the mission, collection of data, review by the self-study committee and production of a report, in preparation for a site visit in the fall of 2008 and follow-up recommendations by an external team.
