Persons Certification Bodies
General requirements for bodies operating certification of persons. Specifies requirements for bodies that certify individuals against defined competence requirements, including scheme development, examination, and certification maintenance.
ISO/IEC 17024 specifies general requirements for bodies operating certification of persons, covering scheme development, examination management, certification issuance, surveillance of certified persons, and appeals processes. It forms the accreditation basis for professional certification bodies globally.
As ACI itself operates under ISO/IEC 17024 principles, ACI-certified auditors of this scheme develop deep understanding of how ACI's own certification framework is designed and governed — including examination quality assurance, scheme committee independence, and certification surveillance mechanisms.
This scheme is particularly relevant for those working in or auditing professional certification organisations, HR qualification bodies, and competence assessment programmes.
Attend an ACI-Approved Training Provider (ATP) course for your chosen grade level. ACI-approved courses are aligned to the examination syllabus for ISO/IEC 17024.
Examinations are administered exclusively through ACI Approved Training Providers. Foundation and Internal Auditor examinations require 70% to pass; Lead Auditor requires 65%.
Submit your application through the ACI portal with your examination result, training certificate, and relevant audit experience log. Upon approval you receive your ACI Card ID and digital certificate.
