Checklist for Clause 8.3 of ISO/IEC 42001 (AIMS): AI Risk Treatment

1. Introduction

Below is a certification-grade, auditor-ready tabular checklist for Clause 8.3 of ISO/IEC 42001 - AI Risk Treatment, developed directly from the PECB auditing slides and expanded into clear, testable, evidence-based audit criteria aligned with PECB / IAS-accredited audit practice.

This checklist ensures AI risk treatments are implemented, verified for effectiveness, adaptive to new risks, revalidated when ineffective, and fully documented.

Audit Checklist (Implementation, Effectiveness, Adaptation & Records)


# Clause 8.3 Requirement Area Audit Objective Audit Questions (Checklist) Expected Evidence Conformance (Y/N/Partial) Findings / Gaps Risk Rating Improvement Actions
8.3-1 Approved Risk Treatment Plan Confirm governance Is there an approved AI risk treatment plan derived from Clause 6.1.3? Approved plan; SoA     
8.3-2 Implementation of Treatments Validate execution Have planned actions and controls been implemented as specified? Control evidence; logs     
8.3-3 Scope Coverage Ensure completeness Do implemented treatments cover all prioritised AI risks? Risk-treatment mapping     
8.3-4 Ownership & Accountability Ensure responsibility Are risk owners and control owners assigned and accountable? RACI; role definitions     
8.3-5 Timeliness Reduce exposure Are treatments implemented within defined timelines? Project plans; milestones     
8.3-6 Verification of Effectiveness Measure outcomes Does the organization verify the effectiveness of implemented treatments? Effectiveness reviews     
8.3-7 Indicators & Metrics Enable monitoring Are indicators/KPIs defined to assess whether treatments achieve intended outcomes? KPIs; dashboards     
8.3-8 Monitoring Mechanisms Ensure continuity Are monitoring mechanisms in place and operating? Monitoring reports     
8.3-9 Treatment of Newly Identified Risks Maintain responsiveness When new AI risks are identified, are treatments selected and implemented in line with Clause 6.1.3? Updated risk register; plans     
8.3-10 Trigger Sources Detect emergence Are new risks captured from incidents, changes, drift, audits, or external factors? Incident/change logs     
8.3-11 Review of Ineffective Treatments Enable correction Are ineffective treatments identified through monitoring or review? Review records     
8.3-12 Revalidation of Treatments Improve controls Are ineffective options reviewed, re-selected, or enhanced per Clause 6.1.3? Revised treatment plans     
8.3-13 Plan Updates Maintain alignment Is the risk treatment plan updated based on review outcomes? Versioned plan updates     
8.3-14 Integration with Operations Embed controls Are treatments embedded into operational processes (see Clause 8.1)? SOPs; process controls     
8.3-15 Change Control Prevent regression Are changes to treatments controlled, approved, and assessed for impact? Change approvals     
8.3-16 Residual Risk Acceptance Formalise decisions Is residual risk evaluated and accepted by authorised management where applicable? Acceptance records     
8.3-17 Documentation Retention Provide evidence Does the organization retain documented information on treatments and outcomes? Stored records     
8.3-18 Content Sufficiency Ensure completeness Do records include identified risks, selected options, actions taken, and outcomes? Completed templates     
8.3-19 Traceability Support audit Can treatments be traced to specific risks, AI systems, and versions? Traceability matrix     
8.3-20 Management Oversight Confirm accountability Does management review treatment effectiveness and residual risk? Management review minutes     


3. Auditor's Conclusion - Clause 8.3

Assessment Area Conclusion
Overall Conformance Status ☐ Conform ☐ Minor NC ☐ Major NC
Effectiveness of AI Risk Treatment ☐ Effective ☐ Partially Effective ☐ Ineffective
Responsiveness to New Risks ☐ Proactive ☐ Reactive ☐ Weak
Residual Risk Governance ☐ Strong ☐ Adequate ☐ Weak

4. Common Auditor Findings (Clause 8.3)

Auditors often raise findings where:

  • Treatment plans exist but controls are not implemented
  • Effectiveness is assumed rather than measured
  • New risks are identified but not treated promptly
  • Ineffective controls are not revalidated
  • Records do not demonstrate outcomes or residual risk decisions

This checklist closes those gaps.

5. ISOLTX Operational Alignment

Clause 8.3 is operationalised through:

  • ERMS → Risk treatment planning, residual risk tracking
  • AUDIT → Verification of treatment effectiveness
  • PERFORMANCE → Control KPIs and trend analysis
  • DMS → Treatment plans, approvals, records
  • I²MAS → Incident-driven treatment updates

It ensures AI risk treatment is dynamic, measurable, and defensible.
