Becoming a consultant and internal auditor

There are no requirements for consultants, if you are able to implement the standard and make the company pass the certification audit, that is all the organization needs from you. There are some courses like Lead Implementer, but I'm not sure if they will really help you. Lead Auditor course you've passed is sufficient to get you familiar with requirements of the standard and now you need to figure out how to implement those requirements. The good start is to see how the standard is implemented in some company and start from there.

I want to know the basic prerequisite for becoming an Internal Auditor. Please respond with the required items that need to be acquired such as training, certificates, experience etc.

the standard does not have requireme nts in terms of competence for internal auditors, but usually they need to be familiar with requirements of the standard and the processes within the company. It can be beneficial for internal auditors to pass either Lead Auditor or Internal Auditor course to get familiar with requirements of the standard and the auditing techniques.

Another thing is, how to select a team of Internal Auditor for ISO 9001:2015 in an organization??? And if there is already a team of Internal Auditor for ISO 9001:2008 then how to transit them to ISO 9001:2015 and what are the prerequisites???

THe best way to pick people for the internal auditor team is to select one person from each process and they should audit each other's work, and this is only in case when the organization doesn't have quality department. If it does, then the team should be comprised from people from the quality department. For auditors that are already familiar with 2008 revision of the standrad, the best option is to get familiar with new requirements and they are ready to get back to the auditing. They do not have to go through new internal auditor training, it is sufficient to attend some training on the new requirements of the standard.
