The initial audit must always be carried out on site, even in the absence of administrative premises and place of delivery of training. Indeed, the texts plan to meet the organization to be audited at least once during the face-to-face cycle, regardless of the training modalities of your organization (face-to-face, distance, AFEST, etc.).
The audit location is chosen jointly with the auditor, according to your wishes. This can be: your home, a meeting room lent by one of your clients, a rented space for the occasion, etc.
