To qualify for an MFT internship, you must be enrolled in a graduate program or be a recent graduate. You usually need a Board of Behavioral Sciences registration and an active registration number to complete an application for an internship. You may also need your fingerprints on file, a current physical, and an up-to-date tuberculosis skin test. Other qualifications include strong interpersonal, critical thinking, and crisis contact skills, as well as medical billing knowledge. Medical centers may have other specific requirements that you must meet to apply. Once you complete your internship and the required hours, you can take the MFT licensing examination.
