Ensuring an organization’s AI management system (AIMS) meets ISO/IEC 42001 requirements starts with a thorough internal audit. This evaluation identifies gaps in AI processes, controls, and documentation that must be addressed before certification. Auditors verify that AI governance—from risk management to performance monitoring—aligns with ISO 42001 clauses. By following a systematic audit approach, organizations can improve their AI processes and demonstrate readiness for ISO/IEC 42001 certification.

Planning the Internal Audit

• Define Scope and Objectives: Decide which parts of the AIMS to audit (for example, specific AI projects or teams) and clarify the audit’s goals. Ensure the scope covers all relevant AI lifecycle stages and regulatory requirements.
• Assemble the Audit Team: Select auditors with knowledge of ISO standards and AI governance. Auditors must be independent of the processes they audit. If needed, bring in external experts in AI or internal audit.
• Review Documentation: Gather AI governance documents such as policies, risk assessments, data management procedures, ...
... training records, and model validation reports. Thorough documentation of AI processes streamlines the audit; see Best Practices for Documenting AI Processes per ISO 42001 - https://punyamacademy.wordpress.com/2025/07/02/best-practices-for-documenting-ai-processes-per-iso-42001/ for more on this topic.
• Develop the Audit Plan and Checklist: Map audit criteria to the ISO 42001 clauses and prepare a ISO 42001 Audit checklist- https://www.globalmanagergroup.com/Products/iso-42001-documents-manual-procedures-checklist.htm/ of items to review. Define methods (interviews, document checks, observations) and set a timeline.
• Schedule and Notify: Schedule the audit activities and hold an opening meeting to explain the scope and process to stakeholders. Ensure participants know their roles and have necessary records ready, which minimizes disruptions.

Executing the Internal Audit

With the audit plan approved, the team conducts the on-site review. Auditors examine AI-related records, observe processes, and interview staff who manage AI systems. They compare findings to ISO/IEC 42001 requirements, noting any gaps or nonconformities. Throughout this phase, professionalism and objectivity are essential.
• Opening Meeting: Reiterate the scope, objectives, and schedule. Clarify any questions and emphasize that the audit aims to evaluate and improve the AIMS.
• Interviews and Reviews: Interview process owners and relevant staff to confirm how policies are implemented. Review procedures, system logs, and reports to verify compliance with AI risk management and data governance requirements.
• Observe Activities: If possible, observe AI-related activities (for example, model validation or data handling) to confirm that documented processes are followed in practice.
• Collect Evidence: Gather objective evidence (screenshots, logs, training certificates, etc.) to support each audit point. Ensure evidence is traceable and relevant.
• Assess Compliance: Check each requirement against the evidence. Note any nonconformities (and classify them by severity) as well as observations for potential improvement.

Documenting Audit Findings

• Record Findings: Record all findings systematically using the checklist or an audit log. Note what was reviewed, the evidence found, and the result. Write clear statements (e.g., “AI risk assessment for Project X was not documented”) and reference the relevant ISO clause.
• Categorize Issues: Distinguish nonconformities from observations and good practices. For nonconformities, cite the specific requirement that was unmet. For observations, describe the context and potential impact.
• Draft the Audit Report: Summarize the audit scope and objectives, highlighting positive practices. List each finding with evidence and include recommendations and an overall assessment.
• Review the Report: Have a lead auditor or quality manager review the draft for clarity and completeness. Then finalize and circulate the report to management and process owners.

Evaluating and Reporting Results

• Closing Meeting: Present the audit findings to management and staff. Discuss each nonconformity and observation so everyone understands the issues.
• Formal Report Distribution: After the closing meeting, distribute the final report. Highlight any critical nonconformities that need immediate action and ensure the report is clear and actionable.
• Management Review: Use audit results as input to the ISO 42001 management review. Leadership should evaluate the findings alongside performance metrics and commit to necessary improvements.

Follow-Up Actions

• Corrective Actions: For each nonconformity, define corrective actions with assigned responsibility and deadlines. Track them in a corrective-action log.
• Implement Improvements: Address the root causes of issues and any observations (for example, update procedures or provide training).
• Verify Effectiveness: Once actions are complete, verify that issues are resolved. This may involve follow-up checks, updated document reviews, or targeted re-audits.
• Update Documentation: Ensure that any changes to AI processes are documented. Keeping records current (as emphasized in Best Practices for Documenting AI Processes per ISO 42001 - https://punyamacademy.wordpress.com/2025/07/02/best-practices-for-documenting-ai-processes-per-iso-42001/ ) will streamline future audits.
• Plan the Next Audit: Schedule the next internal audit cycle (often annually). Use lessons learned from this audit to improve the next one.

Conclusion: Conducting a thorough internal audit is essential for ISO/IEC 42001 certification. By carefully planning the audit, methodically executing and documenting findings, and promptly following up on issues, organizations ensure their AI management system complies with the standard. This process not only prepares the organization for the certification audit but also drives continuous improvement in AI governance and accountability.
