First certification audit checklist
A generic, printable list of practical items to prepare before a first certification audit. It is not a readiness verdict and not a formal audit.
Updated 5 November 2026
This checklist helps you prepare for a first certification audit by an independent certification body. It is generic. It does not reproduce any standard's text, and it does not replace the requirements of the standard you are working to. Completing it does not mean you are ready or that you will be certified. It is not a formal audit, a readiness assessment or a prediction of the result. Only the certification body can audit and decide. To print, use your browser's print command.

Standard-specific items
Add items that come from your standard and your sector. Ask your certification body or a competent adviser. For example:
- Items relevant to environmental aspects, if you work to ISO 14001
- Items relevant to hazards and incidents, if you work to ISO 45001
- Items relevant to information security controls, if you work to ISO/IEC 27001
The days before the audit
- Meeting room and a contact for questions arranged
- Site access and safety induction ready for the auditor
- Key people available at the planned times
- Access arrangements ready, if the audit is partly remote
- Opening and closing meetings scheduled with management
On the day
- Answer the question asked, and say so if you need to check
- Show the work as it is
- Take notes of findings and questions
- Ask for clarification on any finding you do not understand
After the audit
- Findings are recorded and understood
- Corrections and root cause investigations are assigned to named people
- Responses are sent to the certification body within the period it sets
- You know what will happen next, and when you will hear the decision
- Surveillance planning starts: see surveillance and recertification
