Since 2016, Mountain Mission School’s K-12 education program has had joint accreditation by the Association of Christian Schools International (ACSI) and Cognia (formerly AdvancEd).

ACSI exists to strengthen Christian schools and equip Christian educators worldwide as they prepare students academically and inspire them to become devoted followers of Jesus Christ.

The AdvancED accreditation process, a protocol embraced around the world, is a clear and comprehensive program of evaluation and external review, supported by research-based standards—all dedicated to helping schools, districts and education providers continuously improve.
