For management systems consulting or auditing conformity to international management system standards make sure that you are on the right track to become an internationally recognized lead auditor by selecting certified training organizations running certified training courses.

Certified by IRCA or Exemplar Global or your internationally recognized national equivalent.

Whatever your industrial sector, these are my recommended training provider selection criteria. You may also be able to find a course that teaches well the development of process-based management systems,

After passing your certified course modules, keep a log of your system auditing experience and find reputable folk willing to vouch for your competence before applying to become a certified auditor. Then lead the specified number of system audits and apply for international recognition as a certified lead auditor.

This is the track I would recommend. Other courses by other providers may be useful but keep your eye on the prize.
