Authority weight: high for Paul’s decisions and the pathway design (own planning document, decisions confirmed by Paul in-session); medium for exam-mechanics detail — PECB official pages/brochures were used directly, but domain weightings and MCQ question counts come from third-party analysis, not PECB publications

What it claims
Research and pathway document for the PECB Certified ISO/IEC 42001 Lead Auditor exam. Certification mechanics (from PECB course page, brochure, and exam rules): 5-day course structure (day 5 = exam); 3-hour open-book exam (hard-copy standard, training materials, personal notes, dictionary permitted); passing score 70%; PECB migrating Lead exams from 12 essay questions to multiple-choice open-book (80 questions on the Lead Implementer equivalent); retake after ≥15 days, one free retake within 12 months with partner training; self-study candidates may sit the exam without training. Seven exam competency domains, with third-party indicative weightings putting audit methodology (Domains 3–7) at ~75% and “Conducting” heaviest at ~24%. Credential tiers: exam alone yields Provisional Auditor; the Lead Auditor title additionally requires 5 years’ experience (2 in AI) and 300 documented audit hours, applied for within 12 months with references and an audit-activity log. Body of knowledge mapped per domain: ISO/IEC 42001:2023 clauses 4–10, Annex A (9 control objectives, 38 controls), Annexes B–D; ISO 19011:2018; ISO/IEC 17021-1; supporting standards ISO/IEC 22989, 23894, 42005, 42006:2025. Pathway: 12 weeks × 10 h/week (≈120 h) from 20 Jul 2026, four phases (standard → audit methodology → mock audit with Week-8 readiness gate → exam prep), exam target w/c 12 Oct 2026, reusing the IGA Toolkit v1 as mock-audit working papers. Paul’s confirmed decisions (2026-07-18): baseline = strong AI governance / no formal audit certification; route = self-study first, PECB course/exam later; target ≈3 months (Oct 2026).
Notable quotes
- “Plan, conduct, and close an ISO/IEC 42001 compliance audit, in accordance with ISO/IEC 17021-1 requirements, ISO 19011 guidelines” (PECB brochure, learning objectives)
- “No specific set of training courses or curriculum of study is required as part of the certification process” (PECB exam rules — basis of the self-study route)
What’s speculative vs. asserted
- Asserted (PECB official pages/brochure): course structure, exam duration, open-book policy, seven domain names, credential-tier experience requirements, retake policy, self-study permission, 70% pass mark.
- Speculative / third-party: per-domain percentage weightings and the 80-question MCQ count for the 42001 LA exam specifically (extrapolated from the Lead Implementer handbook and a third-party exam guide) [speculative — S-2026-07-18-pecb-42001-la-exam-prep]; the document itself instructs verification against the official LA candidate handbook at booking.
- Planning assumptions: 120 h is sufficient given the baseline; Week-8 gate threshold of 75%.
Topics this feeds

Open questions raised
- Official PECB 42001 LA candidate handbook (question count, domain weightings, current essay-vs-MCQ status) not located during the session — verify when booking.
- Timeline tension: AI Assurance Transition Plan (17 Jul) sets the exam as a September Month-2 exit criterion; the 18 Jul decision targets October. Week-8 readiness gate designated as the reconciliation point — unresolved until then.
- Audit-hours evidence: how quickly IGA engagements structured as ISO/IEC 42001 audits can accumulate the 300 h needed for the full Lead Auditor title.
