How to become a certified ISO internal auditor

Many organizations benefit from implementing one or more of the many ISO-compliant management systems. Whether covering quality, safety, information security, environmental performance or artificial intelligence, being certified to an ISO standard is a major asset for a business to continually improve, provide proof of performance and demonstrate commitment.

For an organization’s management systems to be certified by an independent third party such as DNV, it must first be developed and implemented.  This involves audits by internal auditors who have knowledge of the standard and the organization’s own management structure.

What is an ISO auditor? Meaning and definition

Strictly speaking there is no such thing as an ISO auditor although the term is often applied to a professional equipped with the expertise to assess and evaluate the compliance of an organization's processes and management systems against the internationally recognized ISO standards.

Internal auditors are usually part of the organization seeking certification and may act as qualified auditor ISO certification professionals. External auditors are employed by certification bodies like DNV.  Internal audits are pivotal to ensure that organizations adhere to the rigorous requirements set forth by the ISO standards. ISO does not certify auditors itself – they own the management system standards – but individuals can become certified by bodies such as IRCA after receiving appropriate training and passing an examination.

External auditors of the certifying body must meet the requirements of the ISO 17021 standard which covers the competence, consistency and impartiality of bodies providing audit and certification of all types of management systems.

Certifying bodies like DNV provide internal auditor training courses for specific standards and various levels. An audit team will generally consist of several auditors and a lead auditor.  Learn more about DNV ISO 9001 internal auditor and ISO 45001 Internal Auditor training courses.

What's the difference between an internal auditor and an internal lead auditor?

Audits of an organization’s management systems must be carried out on a regular basis in order for certification to be retained. Internal audits are normally done more frequently by the organization’s own audit team and may be confined to specific risk areas or aspects of the organization. To be certified, external audits by the certification body are achieved annually.

In the context of management systems, the distinction between an internal auditor and lead auditor lies in the scope and focus of their knowledge and auditing activity responsibilities. The latter has a greater knowledge of the audit process and the standard being audited. They head the audit team. Both types of auditors aim to improve organizational processes and ensure compliance with the selected ISO standard(s). A lead auditor would normally have begun as an internal auditor and gained experience of several audits before taking a further extensive Lead Auditor course. These courses are specific to the standards. Discover more about the ISO 9001 Lead Auditor and ISO 14001 Lead Auditor training courses offered by DNV.

How to become an ISO auditor: steps and requirements

Becoming an ISO auditor involves a series of steps and requirements that are designed to ensure you have the necessary knowledge and skills to perform audits to a specific standard effectively.

Training and On-the-Job Experience

It generally involves training and on-the-job experience related to specific ISO-standards for the relevant management system. It is also beneficial to have knowledge of the industry in which the company operates and for external ISO auditors, this is often a competence requirement.

Building an Understanding of ISO Standards

To build an understanding of the ISO standards to which the organization is being audited involves studying the standards themselves, as well as any guidance and interpretation documents that are relevant.

Importance of Training Courses

Training courses such as those provided by DNV will provide knowledge needed to understand and take part in the audit process and enable practical application of the knowledge gained. Training courses often conclude with an exam to test the attendee’s knowledge before it can be signed off as completed.

Achieving Recognition

Depending on the course and provider, the exam may confer an internationally recognised certificate. If not, and upon meeting the requirements of evidence of experience and passing an examination, an internal auditor or lead auditor can apply for membership of an organization such as the International Register of Certified Auditors (IRCA).

Continuous Professional Development (CPD)

Auditors are expected to maintain their skills and knowledge through continual professional development (CPD). This may involve attending additional training courses, participating in industry events, or keeping up to date with changes to the standards.

What are the advantages of becoming a certified internal auditor?

The pursuit of becoming a certified internal auditor comes with a multitude of advantages.

With certification comes the requirement for continual compliance and a focus on improvement. Internal auditors are central to these aspects and certification as an internal auditor is a mark of professionalism that is recognized globally. It can also significantly enhance an individual’s employment prospects.

In summary, becoming a certified internal auditor is not just about gaining a title; it's about embracing a journey of continuous learning, professional development, and contributing to the highest standards of business practices to allow business and the individual to be successful.
