Often, graduate degrees help people advance further in their careers and earn more over a lifetime. Some fields — such as physical therapy — require graduate degrees. Others, such as engineering, encourage them. Students may pursue a graduate degree immediately upon completing a bachelor’s, or they may return to graduate school later.
Graduate education encompasses research, study and teaching beyond the bachelor’s degree. While undergraduate education leads to a bachelor’s degree, graduate education leads to master’s degree and doctorate, also called a doctoral degree.
