Application process

If you are applying to one of the general environmental auditor levels on the register, this is assessed by IEMA using a points system. Points are awarded based on academic qualifications, membership of professional bodies, training and experience. For each registration level, a different points threshold must be reached, and you have to demonstrate skills in environmental auditing appropriate to the level for which you apply. All applicants to the scheme are required to pass a rigorous assessment process involving a combination of references, external verification checks (see below), and for the higher levels, successful completion of an oral examination (also, see below).

External verification checks

For each application received, IEMA contacts the verification sources provided in the application to check that the work was undertaken, for the correct length of time and was of an acceptable standard. IEMA is not interested in the findings of the audit or any confidential information.

Oral examination

The final stage of the Principal Environmental Auditor application process is to undertake an oral examination with two Principal Environmental Auditor Examiners. The examination is face to face and lasts approximately 45 minutes.
