The style of notating a college degree includes information on the level of the degree (bachelor’s, master’s, doctor’s) as well as the general type of degree (arts, science) or specific subject area type (social work, medicine, music). How a college degree is notated is often influenced by the the level of formality of the type of document in which it appears.

How to Refer to a College Degree
