Protocol programs help students discover important information about hospitality management, business tourism and event planning. These programs often include courses over a wide variety of related topics, such as stress management, global travel and entertainment, entrepreneurship and personal branding.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
