Choosing an AS9100 auditor training provider is a decision that follows a quality professional for years. The credential you earn, the CPD hours you accumulate, and depth of knowledge all depend on the quality of the program behind them. For operations leaders evaluating training options for their teams or ISO 9001 veterans looking to add a new certificate to their arsenal, the differences between providers aren’t always obvious from a course description. Here’s what to look for and why each factor matters.
IAQG-Recognized Authentication
The most important credential an AS9100 auditor training provider can carry is recognition through the IAQG certification scheme. Courses approved through a Training Provider Approval Body, are the only courses that contribute toward formal aerospace auditor authentication. A Lead Auditor certificate from a provider without recognition doesn’t carry the same weight in the scheme and won’t satisfy authentication requirements when an auditor applies through IAQG Authentication.
For operations leaders, this is the first filter. Any provider worth evaluating should be able to confirm their training approval status clearly and without qualification.
CPD Hours That Actually Count
Continuing Professional Development hours are both the currency of auditor re-authentication and the metric to measure commitment to quality and improvement . The hours you and your team earn through training need to be traceable, structured, and issued by a recognized provider. Certificates that don’t specify CPD hours, course duration, and provider identity won’t satisfy the documentation requirements for re-authentication under the scheme.
A credible provider issues completion certificates that include the course title, duration in hours, the provider’s name or logo, and a representative signature. It’’s not a bureaucratic detail. It’s the difference between training that counts toward re-authentication and training that doesn’t.
Depth Beyond the Core Credential
A Lead Auditor or Internal Auditor course is a starting point, not a ceiling. The aerospace supply chain touches risk management, first article inspection, counterfeit parts prevention, APQP, PPAP, PFMEA, GD&T, and ITAR compliance. An auditor who understands AS9100 in isolation is equipped for a certification audit. An auditor who understands how these adjacent requirements connect to the QMS is equipped for the work that happens between audits.
Operations leaders staffing quality functions should be looking for providers that offer depth beyond the core credential, courses that build practical competence in the areas their auditors are going to encounter on the production floor and in supplier qualification conversations.
Flexible Delivery Without Compromising Content
Quality teams don’t always have the luxury of sending people to a five-day in-person course. Live online delivery has become a standard expectation for credible training providers, and the best programs maintain the same content, instruction quality, and CPD hour value regardless of format. A provider that only offers one delivery mode is a provider that’s optimized for their own logistics rather than their students’ needs.
The same applies to scheduling. Monthly or frequent course cadences mean organizations can plan training around project cycles, audit schedules, and staffing realities rather than waiting months for the next available seat.
A Catalog That Grows With Your Team
The best training relationships are ones where a provider can support a quality professional at every stage, from first Internal Auditor credential through Lead Auditor authentication and into the specialized knowledge that makes an auditor genuinely valuable to an organization. Providers with narrow catalogs force organizations to piece together training from multiple sources, which creates inconsistency in how teams are developed and makes CPD tracking more complicated than it needs to be.
A provider with a catalog that spans auditor credentials, transition training, core tools, risk management, counterfeit parts prevention, GD&T, and regulatory compliance like ITAR is a provider that can serve a quality team’s needs as those needs grow and change.

AS9100 Auditor Training: Common Questions Answered

What is the difference between an AS9100 Internal Auditor and Lead Auditor course?
Internal Auditor training covers conducting audits within your own organization. Lead Auditor training covers planning, leading, and reporting on third-party certification audits and is required for formal IAQG auditor authentication.
What is Probitas and why does it matter for AS9100 training?
Probitas is an IAQG-recognized Training Provider Approval Body. Courses approved through Probitas satisfy the training requirements for aerospace auditor authentication within the IAQG certification scheme.
How many CPD hours are required for AS9100 auditor re-authentication?
CPD requirements are defined in the IAQG certification scheme and vary by authentication level. Hours must come from structured learning activities delivered by recognized providers and documented with compliant certificates.
Do AS9100 auditors need training beyond the Lead Auditor credential?
The Lead Auditor credential establishes baseline competence. Auditors working in aerospace supply chains benefit significantly from additional training in areas like PFMEA, APQP, counterfeit parts prevention, and first article inspection, all of which connect directly to what auditors encounter in practice.
