High school students should study health, mathematics and the sciences. A high school diploma or equivalent is required. Some EEG technologists have been trained on-the-job, although some employers may prefer to hire individuals with formal post secondary training offered through a hospital or community college. Training includes course work in anatomy, physiology, neurology, medical and computer terminology and technology. Students also receive experience in the laboratory. Graduates of approved formal programs, which are usually 1 or 2 years, receive associate degrees or certificates. Qualified applicants can receive the credential "Registered EEG Technologist" and "Registered Evoked Potential Technologist." Polysomnographic technologists receive their credentials through the Association of Polysomnographic Technologists.
