The specific licensure requirements differ from state to state. There are three components required:
(1) Education – consisting of a doctorate in psychology. States may have specific requirements such as a certain amount of credits in various areas of psychology or a minimum amount of total credits.
(2) Examination – this consists of a written examination, the Examination for Professional Practice in Psychology (EPPP). The EPPP is designed to assess basic, broad general knowledge of psychology
(3) Experience – this consists of a specific number of hours completed under the supervision of a licensed psychologist. The specific number of hours, as well as the nature of these hours, varies from state to state. However, as a general rule, two years of full-time practice are required.
Please note that these are this is a basic overview of requirements in order to be allowed to hold oneself out to the general public as a psychologist. However, many masters level psychologists work in exempt settings, such as government agencies, schools, and universities. (For more about this, please see http://www.op.nysed.gov/prof/psych/psychbroch.htm). Additionally, there are licensed counseling professions, such as a licensed professional counselor, licensed family therapist, which requires a masters degree rather than a doctorate.
