Is the internal auditor course officially recognized?

We issue the Mexican DC-3 certificate, which proves training before the STPS, plus a certificate of attendance and achievement. To audit internally, ISO asks you to demonstrate competence, not a specific registration; international lead auditor registers are a different route with other requirements.

How long is the internal auditor course?

Between 16 and 24 hours depending on the standard and on whether it includes the requirements module, plus the audit practice.

Is there an ISO 9001:2026 course yet?

Yes. We teach the requirements course on the 2026 version and a short update course for those who already know the 2015 version.

Can you deliver it at our plant?

Yes, in any city in Mexico, and it is the best option when the audit practice takes place on your own floor.

How many people per group?

We recommend groups of up to 15 so everyone practices interviewing and writing findings.

ISO courses: internal auditor and understanding the standard

We train your team in ISO 9001, ISO 14001 and ISO 45001: understanding the requirements, internal auditor following ISO 19011 and the ISO 9001:2026 update. Online, live or at your plant, with assessment, audit practice and, in Mexico, the DC-3 training certificate recognized by the STPS.

Which ISO courses does a company need?

Two profiles, mainly. Those who operate the system need to understand the standard: what each requirement asks for and how it is met in their process. Those who evaluate it need internal auditor training based on ISO 19011: planning, interviewing, gathering evidence and writing findings. The standard requires demonstrating that competence; in Mexico, the DC-3 certificate also proves training before the labor authority.

Auditors who learn by auditing
