How To Become A Professional ISO Auditor

Auditors at various levels are essential to maintaining certification in ISO standards. Cavendish Scott offers training and guidance that can help all aspiring auditors whether they want to perform audits as company employees, help conduct internal audits for companies like Cavendish Scott, or work as lead auditors for certifying organizations.  

Lead Auditor Training

The most important course for aspiring auditors to take is the one related to the International Register of Certified Auditors, IRCA ISO 9001:2015—Lead Auditor Training. Cavendish Scott was the first source in the U.S. to offer this class, which is recognized by auditor registration organizations including Exemplar Global. It is essential for registrar auditors and those involved in auditing a quality management system, especially those who interact with lead auditors from certifying organizations.

Before taking the course, participants need to have a solid background in ISO standards, something they can achieve with support from Cavendish Scott. For those who wish to take the IRCA exam and become IRCA registered auditors, IRCA requires knowledge of the following:

  • The Plan, Do, Check, Act, or PDCA, cycle
  • The core elements of a management system and the interrelationship among top management responsibility, policy, objectives, planning, implementation, measurement, review, and continuous improvement
  • The fundamental concepts and the seven quality management principles presented in ISO 9000
  • The relationship between quality management and customer satisfaction
  • Commonly used quality management terms and definitions, as defined in ISO 9000
  • Knowledge of the requirements of ISO 9001

Over the 40 hours of training in IRCA ISO 9001:2015, participants learn from experienced Cavendish Scott instructors who are working in the development, implementation, and auditing of quality management systems. The course includes exercises, group work, role-playing, and a live audit of a local company. Participants leave with all of the comprehensive course materials, including checklists, forms, and other tools.

What Cavendish Scott Seeks

From time to time, Cavendish Scott needs to expand its contingent of auditors, either by adding full-time employees who act as consultants and auditors or by hiring contract auditors for specific assignments.

Ideally, applicants for full-time positions have experience with ISO9001, ISO 13485, ISO 14001, and other standards, as well as experience in auditing. Whether applicants have gaps in experience or not, all new hires receive training and support as needed so they can conduct audits with colleagues and on their own. Full-time applicants also need to have a base in Colorado and the ability to travel extensively, usually five to ten days a month within the U.S,

Cavendish Scott contract auditors are reliable, trustworthy professionals and they usually have auditing, but not consulting, clients with whom they’re already working. Contractors are often required to travel and they are sometimes able to transition into full-time positions with Cavendish Scott. 

Openings are posted as they become available on our employment page. Applicants should submit emails of about 10 lines or 300 words expressing their interest and telling briefly about themselves and their qualifications. While technical requirements are important, Cavendish Scott is most interested in personality and overall ability.

Considerations Around Lead Auditing For Certifying Organizations

Requirements for lead auditors are somewhat vague, but registrars generally prefer that the people they hire as with contractors or full-time auditors are certified either by IRCA or the Registrar Accreditation Board and Quality Society of Australasia. Additional qualifications may also be valuable, as explained in our FAQs How Do I Become an Auditor 

Those who seek to work full-time as lead auditors for certifying agencies often find the work is scarce, poorly paid, disrespected and grueling. Most who complete lead auditor training add the qualification of lead auditor to their resumes and employers understand the value that reflects.
