techimage.pngThe American Association of Sleep Technologists (AAST) is the premier allied health membership association for professionals dedicated to improving the quality of sleep and wakefulness in all people. The AAST is committed to promoting and advancing the sleep technologist profession while meeting the professional and educational needs of more than 4,200 members.

Sleep technologists have a deep understanding of the various diagnostic and therapeutic tools used in a sleep center. These professionals are trained in relevant aspects of sleep medicine so they may assist in the evaluation and follow-up care of patients with sleep disorders. Most sleep technologists are credentialed by the American Board of Sleep Medicine or the Board of Registered Polysomnographic Technologists. For information about sleep technology professions, view the scope of practice developed by the AAST.

Established in 1978 and incorporated in 1986, the AAST was known as the Association of Polysomnographic Technologists (APT) until 2007. A detailed history of the formation and development of the AAST is available.

The AAST encourages the sleep technology profession to maintain the highest level of professionalism and honorable behavior, as stated in the AAST Principles of Ethical Standards.


The American Association of Sleep Technologists (AAST) promotes sleep wellness and leads the sleep technology profession through education, resources, and advocacy.
