A nonconformity is the non-fulfillment of a requirement for accreditation. A nonconformity is not an accreditation decision.

While a nonconformity is not subject to appeal, ANAB provides a process for an applicant or accredited entity to challenge a nonconformity. For more information, see PR 1026, Nonconformity Challenge

As of September 1, 2026, all challenges to nonconformities must be submitted through the Audeee platform.
