Can you actually fail an ISO audit?

Technically, ISO audits don't result in a "pass" or "fail" grade. The audit produces findings — observations, minor nonconformities, or major nonconformities. Certification is granted once any major findings are satisfactorily closed out. The vast majority of audits result in certification with manageable findings.

How common are major nonconformities?

Major nonconformities are uncommon when proper preparation has been undertaken. They typically arise from systemic issues — such as no internal audit being conducted, no management review, or a management system that exists on paper but isn't followed in practice.

Do minor findings affect my certification?

No. Minor findings do not prevent certification from being granted. However, they must be addressed through corrective action, and the closeout is typically verified at your next surveillance audit. Unresolved minor findings can escalate in severity over time.

Can my certification be suspended or withdrawn?

Suspension is possible if major nonconformities are not closed within the required timeframe, or if an organisation repeatedly fails to address findings. Withdrawal (cancellation) is rare and typically only occurs after sustained non-compliance. Both situations are avoidable with proper system maintenance.

What Happens If You Fail an ISO Audit?

ISO audits don't work on a pass/fail basis — but findings still need to be understood and managed. Here's what actually happens.

You Don't "Fail" an ISO Audit

ISO certification audits don't produce a pass or fail result. Instead, auditors raise findings — observations, minor nonconformities, or in rare cases, major nonconformities. The vast majority of audits result in certification being granted, often with a handful of minor findings that need to be addressed over time.

The worst-case scenario is receiving findings that must be closed out before certification can be formally granted. Even then, the process is structured, transparent, and manageable — not a sudden rejection.

UNDERSTANDING FINDINGS

Levels of Audit Findings

Terminology can vary slightly between certification bodies, but most audits use three levels of findings.

Observations (Opportunities for Improvement)

Suggestions from the auditor on areas where your system could be improved. These are not nonconformances and do not require formal corrective action. Think of them as professional recommendations — they won't affect your certification outcome.

Minor Nonconformities

A specific requirement of the standard is not fully met, but the issue is isolated — it doesn't indicate a systemic failure. Minor findings are common, even in well-run organisations. You'll need to submit a corrective action plan, and the closeout is typically verified at your next surveillance audit.

Major Nonconformities

A significant gap where a requirement is not met at all, or a pattern of minor issues that together indicate a systemic failure. Major findings are serious but manageable — they require prompt attention and a defined closeout process before certification can proceed.

MAJOR FINDINGS

What Happens with a Major Nonconformity?

During a Certification Audit

Certification cannot be granted until the major nonconformity is satisfactorily closed out. You'll need to provide evidence of corrective action, and the certification body may conduct a follow-up review or additional audit visit to verify the issue has been resolved.

Additional audit fees may apply if re-verification requires an on-site visit.

During a Surveillance Audit

Your certification usually remains active, but you'll be given a defined timeframe — typically 60 to 90 days — to address and close out the finding. If the issue isn't resolved within that period, your certification may be suspended.

Suspension doesn't mean withdrawal — it means certification is paused until the issue is resolved.

CORRECTIVE ACTIONS

Minor Findings & Follow-Up

Managing minor findings

Minor findings must still be addressed through corrective action. While they don't prevent certification, they need to be resolved — and the closeout is typically verified at your next surveillance audit. Unresolved minor findings can escalate in severity at subsequent audits.

Surveillance audits heavily focus on reviewing previous corrective actions. If findings from a prior audit haven't been addressed, auditors will raise concerns — and what was previously a minor issue may be reclassified as a major nonconformity.

Practical tip: Maintaining an up-to-date corrective action register is one of the most important aspects of audit preparation. It demonstrates that your organisation takes findings seriously and follows through on commitments.

ROOT CAUSES

What Typically Leads to Serious Findings?

Major nonconformities almost always reflect systemic failures — not minor documentation errors. The most common causes include:

No internal audit has been conducted
No management review has taken place
The management system is documented but not implemented in practice
Key registers are significantly out of date across the organisation
Major gaps in compliance controls (e.g. no emergency procedures, no risk assessment)

These issues indicate that the management system isn't functioning as intended — not that a single document is missing a signature. The distinction matters: auditors are assessing whether your system works, not whether your paperwork is perfect.

PREPARATION

The Role of Proper Preparation

Having a structured, compliant management system is half the battle. Implementation matters more than paperwork — auditors want to see that your processes are followed in practice, not just documented. When the system reflects how your business actually operates, audits become straightforward.

Experienced consultants typically focus on the non-negotiable elements: ensuring an internal audit has been conducted, a management review has taken place, and the corrective action process is active and up to date. With these foundations in place, major findings are uncommon.

Check Your Readiness Before the Audit

Use our free ISO gap analysis tool to identify potential findings before your auditor does. Better to find gaps early than during the audit itself.

Most ISO audits result in manageable findings that are resolved through straightforward corrective action. Certification issues are rarely dramatic — they're procedural. With a properly structured management system and a commitment to following your own processes, serious findings are uncommon.
