Neurodiagnostic Tech Certifications Eligibility, Testing & Renewals - AAET, ABRET

Diagnosing brain and nervous system disorders are primarily done with the help of specialized testing. While it is the doctors who interpret the results of the test, neurodiagnostic technicians (NDT) are the experts performing the tests. With the data NDTs collect, doctors have the information they need to diagnose sleep, seizure, nervous system disorders, and more.

To become an NDT, aspiring professionals can receive on-the-job training or complete an education program. These programs typically take between one to two years to complete. Graduates receive either a certificate of completion or an associate’s degree. Students who chose to pursue an education in this field should ensure their program is accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP), as this is a requirement for some certifications and guarantees a minimum level of quality of education.

While certification in the field is not mandatory, it is highly recommended as it provides assurance to employers that the candidate is competent in their field. The two primary certifying bodies for neurodiagnostic techs are the American Association of Electrodiagnostic Technologists (AAET) and the American Board of Registration of Electroencephalographic and Evoked Potential Technologists (ABRET). The AAET offers only the certification of Registered Nerve Conduction Study Technologist (R.NCS.T.), while ABRET offers six different certifications in various competencies.

Neurodiagnostic techs are currently in high demand, according to the Bureau of Labor Statistics. Between 2018 and 2028, there is an anticipated 11 percent increase in jobs for clinical laboratory technologists and technicians, including NDTs. This increase is largely due to an aging population who require additional medical care. Professionals in this field earn $53,120 per year on average.

Continue reading to learn about the various certifications available in this field, eligibility requirements for the exams, and how to prepare for each exam.

Early Preparation in High School to Become a Neurodiagnostic Tech

A high school diploma or GED is the first step towards becoming a neurodiagnostic technician. Completing high school or obtaining a GED demonstrates a commitment to completing a course of education as well as indicating a minimum level of education and competency.

Students interested in pursuing this career should focus on classes such as biology, chemistry, math, and English. Since neurodiagnostic techs often interact with patients, classes such as psychology and sociology can provide valuable interpersonal skills.

Neurodiagnostic techs perform tests that help doctors diagnose brain, neurological, or sleep disorders. Performing these tests requires training or education on specialized equipment as well as excellent interpersonal skills to comfort patients. Certification in this field is optional albeit highly recommended. Below are the top two certifying agencies and the certifications they offer.

American Association of Electrodiagnostic Technologists (AAET) Registered Nerve Conduction Study Technologist (R.NCS.T.) Certification Eligibility

In order to be eligible to sit for the AAET R.NCS.T. exam, candidates must qualify under one of two pathways. The pathways are:

  • Have one year of experience and proof of 100 patient encounters or have one year of experience and complete 30 AAET continuing education units (CEUs)
  • Complete a neurodiagnostic technology (NDT) program accredited by CAAHEP and have proof of 100 patient encounters or complete an NDT CAAHEP-accredited program and complete 30 AAET CEUs

In addition to meeting education or experience requirements, candidates must complete an AAET Attestation Statement that verifies that the applicant is not performing invasive (i.e., needle) exams and that the interpretations are completed by the physician. If the state or regional regulations allow neurodiagnostic techs to perform invasive procedures, applicants must supply a copy of a superseding certificate that allows invasive exams and interpretation.

To take the exam, candidates must complete an application, pay the $625 application fee, and provide a copy of their certification card for Basic Life Support (BLS) for the Healthcare Provider issued by the American Heart Association.
