Good Afternoon, I'm hoping someone can clarify the need for lead auditor training. I manage an ISO 9001:2008 and AS 9100 quality system and am responsible for internal audits. I have had internal auditor training but not lead auditor training. Hopefully someone can answer the questions below for me. 1. Am I required to have Lead auditor training to train (not certify) new internal auditors? 2. What is the benefit to receiving lead auditor training if I am already acting at the lead auditor during internal audits? I'm struggling with finding the benefit of the high cost of training as well as the 4-5 days of work I would be missing. Thank you for any feedback.
