Electroneurodiagnostic Technologist (ET)

Electroneurodiagnostic technologists, sometimes known as electroencephalographic or EEG technologists, use an EEG machine to measure electrical activity of a patient’s brain waves to assist in diagnosing brain and nervous system disorders such as brain tumors, strokes, or epilepsy.


Polysomnographic Technician – These technicians use a polysomnograph to measure electrical activity of the brain waves to assist the physician in diagnosing and treating sleep disorders.

Work Activities/Work Locations

Electroneurodiagnostic technologists work in hospitals, psychiatric facilities, or for neurosurgeons and neurologists in private offices and clinics, and health maintenance organizations (HMO’s). They are trained to prepare patients for testing, to operate an EEG machine, and monitor the patient’s brain activity. Some technologists work in the operating room, or they may monitor a patient during daily activities. In addition, they may be required to write a summary of test results, keep records, schedule appointments, order supplies, and arrange work schedules. Standing, bending and lifting are standard activities of the job, although about half of the time technologists are on their feet. Most work a 40-hour work week, and they may be on call to work evenings, weekends or holidays.

Getting Started

  • High School Courses

    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.
