Auditor competence and professional development
Competence is not qualification
Competence is the ability to apply knowledge and skills to achieve intended results. It rests on a blend of education, work experience, auditor training and audit experience, plus personal behaviour. Certificates are inputs to the judgement, not proof of it.
What a competent auditor looks like
ISO 19011 lists personal behaviours: ethical, open-minded, diplomatic, observant, perceptive, versatile, tenacious, decisive, self-reliant and collaborative. Generic knowledge covers audit principles, methods and management system standards; discipline-specific knowledge covers the sector, legal and regulatory requirements, technical processes, products and risks. Audit team leaders additionally need planning, leadership, delegation and report-writing skills.
Evaluation and development
Competence must be defined for each role, evaluated and maintained. Useful evaluation methods include reviewing audit reports, observing audits, interviewing the auditor, peer review, and feedback from auditees and clients. Continuing professional development keeps knowledge current: standard revisions, sector developments, regulatory change, and calibration with other auditors through joint audits or technical meetings.
Trap: assuming a senior engineer or technical expert is automatically a competent auditor - auditing skill is separate from technical skill.
Trap: assuming a one-off assessment is permanent; competence must be re-evaluated as standards, sectors and roles change.
Trap: conflating competence with impartiality - a highly skilled auditor can still be conflicted, and both must be managed.
Rule of thumb
If you cannot point to a record - training, observation, report review, feedback - that demonstrates the competence, treat it as unproven and raise a development action.
