Third-party accreditation is a powerful way of assuring stakeholders that your credentialing program meets exacting standards. Authentic Testing has a perfect track record of supporting certification programs with accreditation against ISO/IEC 17024 through the American National Standards Institute (ANSI) and against NCCA standards through the National Commission for Certifying Agencies (NCCA).
For certificate programs, the relevant standard is ASTM E2659.
