What evidence of training do aerospace auditors typically request?

Aerospace auditors typically request objective evidence that personnel are trained and competent for the work they perform. This usually means more than a sign-in sheet. Auditors often sample an operator, inspector, planner, or supervisor against a live job, then ask for records showing the person was qualified to the correct procedure, work instruction revision, process, customer requirement, or special process before the work was performed.

The exact evidence depends on the audit scope, customer flowdowns, AS9100 implementation, special process requirements, internal procedures, and the site’s own training control process. Auditors do not expect every company to use the same system, but they do expect the records to be controlled, retrievable, current, and consistent with how the organization says training is managed.

Common training evidence auditors ask to see

• A training matrix showing required training by role, work center, process, product family, program, or certification level.
• Individual training records with employee name or ID, course or document title, completion date, trainer or approver, and status.
• Evidence that training was tied to the correct revision of a procedure, work instruction, inspection plan, specification, or controlled document.
• Qualification or authorization records for inspectors, special process operators, source inspectors, final acceptance personnel, or other controlled roles.
• On-the-job training records, practical demonstrations, skill checks, or supervisor signoffs where classroom training alone is not sufficient.
• Evidence of training effectiveness, such as exams, observed competency, first-piece review, periodic reassessment, or documented evaluation criteria.
• Retraining records after procedure changes, nonconformances, escapes, corrective actions, customer complaints, or process changes.
• Expiration and renewal records for certifications, stamps, eye exams, nondestructive testing qualifications, soldering, welding, torque, crimping, or other controlled skills where applicable.
• Records for temporary labor, contractors, transferred employees, and personnel working across multiple shifts or sites.
• Record retention evidence showing that training records are retained for the required period and remain legible and retrievable.

How auditors usually test the evidence

Auditors commonly work from the job backward. They may choose a completed work order, traveler, inspection record, nonconformance, or shipping record and identify who performed or accepted the work. Then they ask whether that person was trained and authorized at the time the work occurred.

They may also work from the training system forward. For example, they may choose a procedure revision released through document control and ask which employees were affected, when retraining occurred, and whether any work was performed before retraining was complete.

This is where weak integration between systems becomes visible. Training may be stored in an LMS, employee qualifications in HR, controlled documents in PLM or QMS, job execution in MES, and labor or routing data in ERP. If those systems do not align, the organization usually needs clear manual controls, reconciliation steps, and ownership. Full replacement of these systems is often unrealistic in brownfield aerospace environments because of validation cost, qualification burden, downtime risk, integration complexity, and long equipment and program lifecycles.

Evidence that is often not enough by itself

A sign-in sheet, read-and-understood checkbox, or generic annual training record may be accepted for low-risk awareness training, but it is often weak evidence for controlled production or inspection work. For task-specific work, auditors usually look for a link between the person, the requirement, the document revision, the effective date, and the work performed.

Common failure modes include stale training matrices, missing revision references, expired qualifications, inconsistent employee names across systems, undocumented grandfathering, informal supervisor approval, and training records that cannot show whether the person was qualified before the job was executed.

What matters most

The strongest training evidence is traceable, current, role-specific, and connected to controlled work. It should show who was trained, what they were trained on, which revision applied, when the training was effective, who approved or verified it, and whether any periodic requalification was required.

No training record structure guarantees a favorable audit outcome. The records need to match the organization’s documented procedures, customer requirements, regulatory obligations, and actual shop-floor practice. If the site relies on manual controls, those controls need to be consistently followed and auditable.
