About A-STEP

The American Academy of Sleep Medicine (AASM) developed the Accredited Sleep Technologist Education Program (A-STEP) to promote the standardization of sleep technologist education and training. A-STEP equips students with the knowledge and skills they need to excel in the profession of sleep technology.

A-STEP is a requirement for sleep technologist certification programs. For information about A-STEP requirements to become eligible to sit in for the Sleep Technologist Registry (RST) Examination, please visit the American Board of Sleep Medicine at Candidates seeking RPSGT certification can find eligibility requirements at the BRPT website.
