Initial by examination
- Application
- Apply through myPECB after passing; PECB validates requirements before award. The training-package cycle includes first attempt, one free retake, certification application and first-year AMF, within 12 months of instructor-led completion or self-study/eLearning purchase. Certificate application has the same stated twelve-month timing. Reopening a closed case requires written request and fee under then-current conditions.
- Audit Experience
- Audit activities totaling 300 hours, validated by PECB. The handbook lists planning audits, managing an audit program, reports and working documents, documented-information review/management, on-site audits, following up nonconformities and leading an audit team as valid audit activities.
- Ethics
- Signing the PECB Code of Ethics.
- Exam
- Pass the named PECB Lead Auditor exam or an equivalent accepted by PECB. Equivalence from recognized accredited certification bodies requires PECB evaluation; no additional named alternative examination is specified. This open equivalence condition does not create a fabricated exam or no_exam branch.
- Maintenance
- Personal certifications are valid for three years, subject to CPD and annual maintenance fees. This individual term and package/application deadlines are not exam-version retirement dates.
- Professional Experience
- Five years of professional experience, including two years of work experience in quality management.
- References
- Two professional references who worked with the applicant and can validate expertise and work history; subordinates and relatives cannot serve.
- Scheduling
- Selected form is English online multiple-choice. Booking requires a published session with available seats in myPECB. Sessions are published bi-weekly; no particular seat throughout 2026-11-25 through 2027-02-28 is guaranteed. Partner-arranged paper delivery is the same exam, not a separate requirement.
- Training
- No specific training is mandatory for this certification exam. The optional course expects fundamental ISO 9001 QMS understanding and comprehensive audit-principles knowledge. Direct booking without training includes one attempt and no official training materials; a certification fee applies after passing.
