A degree is a certificate or diploma awarded by a college, university, or other educational institution to recognize the completion of a course of study. Degrees typically indicate a level of education and knowledge in a particular field, such as arts, science, engineering, or business. The most common types of degrees are associate’s, bachelor’s, master’s, and doctoral degrees, which vary in terms of the length and depth of study required to earn them. Degrees can be earned on-campus or online, and can be used to pursue further education or employment opportunities. Obtaining a degree often requires passing a series of exams, completing coursework, and writing a thesis or dissertation.
