For how long should field notes and interview results be retained by auditors?

The retention of field notes and interview results for at least twelve months is essential for several reasons. First, it aligns with standard auditing practices that emphasize the importance of maintaining comprehensive documentation for sufficient time after the completion of the audit. This retention period allows for referencing the notes during follow-up audits or in response to enquiries about previous audits.

Additionally, retaining notes for this duration supports transparency and accountability within the auditing process. It also provides auditors with the ability to address any disputes or clarify findings that may arise after the audit has been completed. Preserving this information for at least twelve months ensures auditors have sufficient background to provide context and justification for their audit conclusions, thereby enhancing the overall quality and integrity of the audit.

Shorter retention periods, such as six months, nine months, or one year, may not provide adequate coverage for these purposes, particularly in cases where longer-term follow-up is necessary. This underscores the importance of adhering to the minimum retention guidelines to uphold the rigor and reliability of audit practices.
