According to the registered auditor network, anyone who can still be an auditor after the age of 45 can apply for the exam. Auditors are individuals who have received systematic training, passed the examination, been examined by authoritative certification bodies, and have the quality and ability to engage in audit work.

Levels: IRCA registration usually involves five auditor levels, but please note that not all projects have five registration levels, and each applicant can only register one level.
