Lead Auditor Course vs. Lead Implementer Course – Which one to go for?

If you are just entering the world of ISO 27001 or ISO 22301, you’re probably considering going for some training. This is certainly a good idea; however, which course is better for you – Lead Auditor Course, or Lead Implementer Course?

Everything you’ll read in this article is valid not only for ISO 27001 and ISO 22301 courses, but also for ISO 9001, ISO 14001, and ISO 20000 courses.

What do these courses look like?


Both the Lead Auditor and Lead Implementer courses last for five days, and on the fifth day you have to pass an exam; both courses are quite intense, and normally you have to attend 40 hours in 5 days.

On the first day of the course, you will take a detailed look into each clause of the standard, and a tutor will teach you how to interpret the standard, as well as the underlying logic. After this first day, the Lead Auditor course will focus mainly on auditing techniques of the particular standard, while the Lead Implementer course will explain the best methods for implementation.

Most of the courses are quite interactive – e.g., the courses I delivered had about 15 workshops during these 5 days, which gave students a perfect opportunity to learn while doing the group work; of course, there are also lectures, and a good tutor will encourage discussion and applicability of the standard to real situations.

You do not need any special knowledge to enroll in the course – if you go for the ISO 27001 or ISO 22301 course, it is enough to have average knowledge of IT, and no prior knowledge of information security or business continuity is needed.

The main differences

Lead Auditor courses can (and should) be accredited (see next section about choosing the training provider), while there is no accreditation for the Lead Implementer course.

However, the main difference between these two courses is in their focus. If you want to focus your career on auditing, you should definitely go for the Lead Auditor course; if you are a practitioner who is focused on implementation, you should go for the Lead Implementer course. If you are in a consulting business, you should probably go for both, because this is how you’ll learn not only the implementation techniques, but also the certification auditor’s criteria; not to mention that the more certificates you have as a consultant, the more valuable you are.

Which training provider to choose?

These courses are usually provided by the certification bodies, but also by specialized training organizations. You should just search the Internet for the certification bodies in your country, and chances are that you’ll find such courses locally.

When choosing a training provider, you should look for Lead Auditor courses that are accredited by IRCA or RABQSA – this means that, once you pass the exam, this certificate will be accepted by any certification body if you choose to work as lead auditor for them.

There are no accreditations for the Lead Implementer course, so your first criteria when choosing a course should be the tutor – if this person has a good reputation, chances are you will attend a high-quality course.

Invest time in your education

It is true that being absent from work for five whole days may sound like science fiction to you, so if you do not plan to focus your career on ISO standards you could go for one- or two-day courses – see a list here: How to learn about ISO 27001 and BS 25999-2.

However, if you seriously plan to have a career in ISO 27001 or ISO 22301, these five days will be a crucial investment for you. Believe me, not only will you get the certificate (which is a must if you want others to recognize you), but you will also learn the essence about these standards – something you won’t be able to do just by reading the standard from time to time.

    Hi Dejan, Thank you for your article. In addition to IRCA or RABQSA, is there any accredited organization for ISO 27001 Lead Auditor Certification? Is PECB an accredited organization?

  6. Visweswaraiah Dudekula says:

    Hi.. I am in a dilemma, whether to take IRCA Accredited Lead Auditor certification or PECB Accredited Lead Auditor certification progam? Please suggest.

    Thank you very much Dejan for the information. Was quite helpful to understand the difference. Unfortunately With the course prices for lead implementer or lead auditor, continuous professional development to enrich your profile as a freelance auditor and consultant is financially draining. I reckon Lead implementer is quite expensive compared to LA. Any guidance here for cost effective training with a recognised organisation? Thank you in advance for the advice.

    • Not sure if I understood your question correctly, but I think that Lead Auditor and Lead Implementer courses have roughly the same price since their duration is the same.

      You should ask for quotes from several training providers to learn about their pricing.

      • Dima Faour-Klingbeil says:

        Thank you. Thought there may be a well known provider for their rational pricing. Lead implementer was far more costly than LA . I find it irrational these high prices of LA courses .Then one hardly find a CB to shadow audit in order to attain “provisional” auditor unless employed by the CB etc… all the bset
