ISO Transition, Conversion, Refresher & Extension Course Options

Man confused over the difference among ISO transition, migration, conversion, and extension courses

The way to stretch your budget and still get your ISO Internal Auditors certified!

Selecting the appropriate ISO Auditor Training Course can be difficult and confusing with apparently random choices in course titles.

People who have been browsing around for ISO auditor courses are probably already familiar with Internal Auditor and Lead Auditor courses. However, the number of people who are familiar with ISO transition courses, migration courses, conversion courses, and extension courses are probably not as many.

Transition vs Migration vs Conversion vs Refresher vs Extension Courses

While there is no 'official' set of definitions, the table below gives the most frequently used definitions for these terms as they have appeared over the past 20+years.  And there is a clear distinction between, for example, an ISO 9001:2015 Transition Course and an ISO 9001:2015 Conversion Course.  But are you sure of what that distinction is? Let's see ...

ISO Transition Courses

What are ISO transition courses?

Transition Courses provide guidance and recommendations for the required modification for an existing management system that is compliant and certified to a current standard (say, ISO9001:2008). This is so it will comply with a new or revised standard (say ISO 9001:2015)  Typical duration: 18 hours/3 days.

ISO Conversion Courses

What are conversion courses?

With the introduction of many revised and new ISO Management System Standards certified ISO Auditors find that their Certification is out of date.  Conversion Courses bring the Auditor's knowledge of the new/revised Standard up-to-date and provide Auditor Certification to the new/revised Standard.  

Typical Duration of Conversion Courses:

10 hours/1-2 days at Internal Auditor level and 20 hours/3 days at Lead Auditor Level.

ISO Refresher Courses

What are refresher courses?

Our policy has been to not time-limit our Certificates.  We consider the 3-year limit to certificate validity to be little more than a money-making racket.  We have left it to the cycle of revisions to the Standards to prompt our Certificated Learners to take Conversion Courses;  that is, to update only when necessary. This policy has worked well until now when ISO has failed to revise old Standards.  We have Certified Learners who have last trained seven years ago. It’s now well gone the time when retraining is justified and so we introduce the Refresher Courses.

Typical Duration of Refresher Courses:

10 hours (or 1-2 days) at Internal Auditor level and 20 hours (or 3 days) at Lead Auditor Level.

Who should take a refresher course?

If it's been 5 years or more since you had ISO Auditor training, chances are you're 'rusty' and would benefit from a refresher course.  The beauty of our e-learning based courses is that they are self-paced and you can speed through the course content (unlike conventional classroom training or those boring videos).  So, if you are 'rusty' or have done little auditing lately, we very much recommend a refresher course.

What are the prerequisites to taking refresher courses?

Training and certification as an Internal or Lead Auditor in the Standard being updated.

ISO Extension Courses

What are extension courses?

Many auditors would like to add to the certification they’ve already got.  But with conventional training, the only extension of scope options are full 2-day or 5-day courses.  And who can justify that time and expense?  Extension are an effective and time-friendly alternative.  

Typical duration of ISO Extension Courses:

10 hours/1 day at Internal Auditor level and 20 hours/3 days at Lead Auditor level.

Who should take extension courses?

Those wishing to add other ISO Standards to their existing ISO Auditor Certification (e.g. you have ISO 14001 Lead Auditor Certification and you want to add ISO 9001:2015 Lead Auditor Certification)

What are the prerequisites to taking extension courses? 

Training and certification as an Internal or Lead Auditor in a Standard other than the one being updated.

New call-to-actionIn  October 2021 we secured certification to three education-related ISO Standards.  We now have a university-grade management system in place conforming to the requirements of  …

  • ISO 21001, Educational Organizational Management System,
  • ISO 29993, Learning Services outside formal Education,  and
  • ISO 29994, Learning Services – additional requirements for Distance Learning.

We have chosen ISO 21001 certification because, unlike IRCA and Exemplar badges (which in our opinion are commercially compromised), it is based on independent third-party assessment.  It is a ‘university grade’ standard in use globally by schools, colleges, and universities to demonstrate their competence.
