The supplier will not be notified of the assessment's result (supplier category) by default. However, depending on the settings specified by the owner, a notification of the result may be sent to the supplier. This is a customized configuration setting that is determined by the organizer company. This setting might be different for each assessment you take part in as a supplier.
Other than the options available in the system, the organizer may opt to notify the participants about the assessment results outside the system, e.g. via email or phone.
