Alternative grades, regrading and fees

Alternative grades

If you do not meet the auditing requirements for this grade but you have completed the relevant training, did you know you can join us as an Auditor or Associate Auditor?

Associate Auditors do not require any auditing experience and can access many of the same member benefits including their name on the IRCA register and you will be able to regrade once you have conducted the required number of audits.

If you have been conducting audits but not leading an auditing team, please take a look at the requirements for Auditor.


You may regrade at anytime during your membership to an alternative IRCA grade. You will not need to pay an additional membership fee to regrade however a small regrade fee is due to process your application.


For all new membership applications, there are two fees to pay; a one-off application fee to process your application and an annual membership fee. The annual membership fee for IRCA covers a 12 month period (1 year). A membership fee will be due for each scheme you are registered on. For a link to the fees, please click here.
