People normally need eight to 12 years of study to become a licensed clinical psychologist. This includes the time needed to get an undergraduate degree and doctoral degree. The exact amount of time depends on the person's career interests and specialities.
Aspiring psychologists need to get an undergraduate degree in psychology or a related subject, such as social work, education or sociology. Students can then enroll in a doctoral program in clinical psychology. A Ph.D. in psychology focuses on research and scientific principles. A Psy.D. focuses on professional practice and clinical work. People who wish to work as family and marriage therapists normally only require a master's degree.
