Complaints and Appeals in the Certification Process

Certification bodies operating under accredited schemes are required to maintain formal mechanisms for handling complaints and appeals — two distinct procedural categories that protect the integrity of certification decisions and the rights of affected parties. This page covers how those mechanisms are defined under international standards, how each process unfolds in practice, and where the decision boundaries between complaint and appeal procedures lie. Understanding these processes is essential for organizations that receive adverse certification outcomes or observe conduct by a certification body that may violate accreditation requirements.

Definition and scope

A complaint is an expression of dissatisfaction directed at a certification body, a certified client, or the certification scheme itself, where a response is expected. An appeal is a request by a certification applicant or certified organization to reconsider a decision made by the certification body — specifically decisions about the granting, maintaining, suspending, withdrawing, or expanding of certification scope.

ISO/IEC 17021-1:2015, the foundational standard governing conformity assessment bodies performing audits of management systems, explicitly requires certification bodies to have documented processes for both complaints and appeals (Clauses 9.7 and 9.8). These are not interchangeable procedures. A complaint targets conduct or service quality; an appeal targets a formal certification decision. Conflating the two leads to procedural misdirection and delayed resolution.

Scope boundaries matter here. Accreditation bodies such as ANAB (ANSI National Accreditation Board) and A2LA (American Association for Laboratory Accreditation) assess whether certification bodies comply with these procedural requirements during accreditation evaluations. Failure to maintain compliant complaints and appeals procedures can result in accreditation suspension — a point explored further in the certification-suspension-withdrawal page.

The complaints mechanism also extends outward: third parties, such as customers or competitors of a certified organization, may file complaints alleging that a certified entity's conduct does not conform to the certified standard's requirements.

How it works

Complaint process — structured breakdown:

  1. Submission — A complainant submits a written complaint to the certification body. ISO/IEC 17021-1 requires the body to acknowledge receipt and provide an initial assessment of whether the complaint is valid and falls within scope.
  2. Investigation — The certification body assigns personnel with no prior involvement in the subject matter to investigate. This impartiality requirement is codified in Clause 4.3 of ISO/IEC 17021-1.
  3. Decision — A determination is reached, communicated in writing to the complainant. If the complaint involves a certified client's nonconformity, the certification body may initiate corrective action requirements against that client.
  4. Close-out — Outcomes are documented and retained as certification records.

Appeals process — structured breakdown:

  1. Notice of adverse decision — The certified or applicant organization receives a formal decision (e.g., denial of certification, withdrawal).
  2. Appeal submission — The organization files a written appeal within the timeframe specified by the certification body's procedures — typically 30 to 90 days from the decision date, though the specific window varies by scheme.
  3. Independent review — ISO/IEC 17021-1 Clause 9.8.3 requires that the appeal be reviewed by personnel different from those who made the original decision, and that no conflicts of interest affect the review.
  4. Final determination — The certification body issues a final written decision on the appeal. This decision must be made by, or reviewed by, persons not previously involved in the certification decision under review.
  5. External recourse — If the appeal is exhausted internally, the organization may escalate to the accreditation body (e.g., ANAB or A2LA) or, in regulated sectors, to the relevant federal agency.

The certification-decision-process page details how initial decisions are structured prior to reaching the appeals stage.

Common scenarios

Three scenarios account for the majority of formal complaints and appeals in US certification practice:

Adverse audit findings leading to denial — An organization disputes the auditor's characterization of a finding as a major nonconformity rather than a minor one. This is an appeal scenario because it challenges a decision affecting certification status. The distinction between major and minor nonconformity is defined in Clause 3 of ISO/IEC 17021-1 and is further addressed in nonconformity-handling-in-certification.

Auditor conduct complaints — A certified organization reports that an auditor behaved in a manner inconsistent with the certification body's code of conduct — for example, disclosing confidential business information. This is a complaint, not an appeal, because no certification decision is being contested.

Scope boundary disputes — A certified organization appeals a decision that excluded a specific site or process from the certification scope. Scope determinations are formal decisions subject to appeal under ISO/IEC 17021-1.

In regulated sectors — medical devices (FDA 21 CFR Part 820), food safety (FSMA-related programs overseen by FDA), and organic certification (USDA National Organic Program, 7 CFR Part 205) — appeals may carry additional regulatory weight because certification status directly affects market access or legal compliance standing.

Decision boundaries

The critical boundary between complaints and appeals is the presence or absence of a formal certification decision. Appeals require a written adverse decision as a predicate; complaints do not.

A second boundary separates internal appeals from external escalation. Certification bodies are required to exhaust their internal appeals procedures before an applicant can effectively engage the accreditation body. ANAB's published appeals procedures specify that accreditation-level review is available only after the certification body's internal process is complete.

A third boundary governs who makes the decision. ISO/IEC 17021-1 prohibits the same individual who issued the original certification decision from ruling on the appeal of that decision. This structural separation is a mandatory impartiality control, not a discretionary practice.

Personnel certification schemes follow parallel but distinct rules under ISO/IEC 17024:2012, which governs bodies certifying persons. Under Clause 9.9 of that standard, both complaints and appeals must be managed through documented, independent processes — the same structural logic as ISO/IEC 17021-1 but applied to individual credential decisions rather than organizational management system certification.
