Our section offers the Accredited Sleep Technologist Education Program (A-STEP) to promote the standardization of sleep technologist training; an initiative of the American Academy of Sleep Medicine (AASM).

In July of 2006, we became one of the first sites in the nation to receive accreditation from the AASM as an A-STEP provider, meeting the standards after detailed evaluation of our program, including faculty, curriculum, resources and assessment.

Participants will receive an accredited education and training that develops a sleep medicine knowledge base and the professional skills required of a sleep technologist.

Our A-STEP training is a significant resource to the local community as it ensures that those who assist in the diagnosis and treatment of patients with sleep disorders are well-trained and that patients suffering from sleep disorders receive the highest quality of care.


Completion of A-STEP is a two-step process:

  • A-STEP introductory course: 80 hours of instruction and training on sleep, sleep disorders, sleep studies and patient care. The program concludes with a three-hour online exam consisting of 106 multiple-choice questions.
  • A-STEP self study modules: Each of the 26 A-STEP self-study modules includes a 60-minute online video presentation followed by a set of 10 review questions. Students are encouraged to complete the online modules while working in the field. Trainees that complete the A-STEP introductory course and final exam will receive a discount on the modules

Students whom complete both steps will be eligible to take the Board of Registered Polysomnographic Technologists (BPRT) registry exam once 819 hours of experience in the field have been obtained. Students with another healthcare credential will be eligible to sit for the exam once 546 hours have been obtained.

A: After successfully passing our program, we will notify the (AASM) and they will send you information regarding an online examination.  You will need to pass the online exam with a score of 70% or greater.  Next, there is a series of 26 online AASM modules to complete (there is an additional fee for the online exam and modules).

Q: How do you become certified or registered in the field of sleep technology?

A: The Board of Registered Sleep Technologists offers a certification and registry exam for sleep technicians. The American Board of Sleep Medicine offers a registry exam for sleep technologists. For more information about the exams, please visit the American Board of Sleep Medicine or the Board of Registered Polysomnographic Technologists.
