Registered Respiratory Therapists (RRTs) and Certified Respiratory Therapists (CRTs) can perform sleep technology tasks within their licensure and certification scope, especially if they possess a sleep disorders specialist credential (CRT-SDS or RRT-SDS). Permitted duties, within scope and training, include preparing and hooking up patients, monitoring during sleep studies, and scoring sleep studies when properly credentialed or supervised as specified below. **For credentialing and supervision:**   - Independent scoring requires certification as a sleep disorders specialist (CRT-SDS or RRT-SDS) or other accepted credentials (e.g., RST, RPSGT, CPSGT), in alignment with AASM standards.   - Non-certified respiratory therapists may perform technical duties, but credentialed sleep specialists must supervise scoring. **Regarding licensure and training:**   - Maintain a valid, unrestricted respiratory therapist license in accordance with state law and practice within the scope of licensure. If not registered, complete AASM-recognized polysomnography training programs or the ASTEP Introduction to Sleep Medicine for Technologists Modules.   - Technologists and therapists who are not registered must finish the ASTEP Introduction to Sleep Medicine for Technologists Modules or an approved polysomnography program within two years.   - Follow AASM Standards N-8 to N-14 concerning the training, licensure, and supervision of technical staff such as RRTs and CRTs. - [ASTEP](https://support.aasm.org/astep?hsLang=en#main-content) - [ASTEP Online Modules](https://support.aasm.org/astep?hsLang=en#astep-online-modules) - [Find an ASTEP Introductory Course Provider](https://support.aasm.org/astep?hsLang=en#find-an-astep-introductory-course-provider) - [State Board Requirements for becoming a CPGST](https://support.aasm.org/astep?hsLang=en#state-board-requirements-for-becoming-a-cpgst) - [ASTEP Registration](https://support.aasm.org/astep?hsLang=en#astep-registration) - [Clinical Experience or Focused Training](https://support.aasm.org/astep?hsLang=en#clinical-experience-or-focused-training) - [Clinical Guidelines & Research](https://support.aasm.org/clinical-guidelines-research?hsLang=en) - [Education, Courses & Meetings](https://support.aasm.org/education-courses-meetings?hsLang=en) - [Membership](https://support.aasm.org/membership?hsLang=en#main-content) - [Renew/Join AASM Membership](https://support.aasm.org/membership?hsLang=en#renew-join-aasm-membership) - [AASM Membership Invoices](https://support.aasm.org/membership?hsLang=en#aasm-membership-invoices) - [directory/list](https://support.aasm.org/membership?hsLang=en#directory-list) - [Patient Information](https://support.aasm.org/patient-information?hsLang=en#main-content) - [Patient Questionnaires and Forms](https://support.aasm.org/patient-information?hsLang=en#patient-questionnaires-and-forms) - [Cognitive Behavior Therapist (CBT-I)](https://support.aasm.org/patient-information?hsLang=en#cognitive-behavior-therapist-cbt-i) - [Products & Orders](https://support.aasm.org/products-orders?hsLang=en#main-content) - [What is the process for submitting a request for a damaged product?](https://support.aasm.org/products-orders?hsLang=en#what-is-the-process-for-submitting-a-request-for-a-damaged-product) - [Purchase Order (PO) Instructions](https://support.aasm.org/products-orders?hsLang=en#purchase-order-po-instructions) - [Products For Technicians](https://support.aasm.org/products-orders?hsLang=en#products-for-technicians) - [Site-Licensed and On-Demand Videos](https://support.aasm.org/products-orders?hsLang=en#site-licensed-and-on-demand-videos) - [Sleep ISR](https://support.aasm.org/sleep-isr?hsLang=en#main-content) - [Frequently Asked Questions](https://support.aasm.org/sleep-isr?hsLang=en#frequently-asked-questions) - [Tutorials](https://support.aasm.org/sleep-isr?hsLang=en#tutorials) - [General Inquiry](https://support.aasm.org/general-inquiry?hsLang=en) [![Chill listening crop-3](https://support.aasm.org/hs-fs/hubfs/AASM_logo_mark_RT_rgb.png?width=61&height=24&name=AASM_logo_mark_RT_rgb.png "Chill listening crop-3")](https://aasm.org) AASM Help Center Copyright © 2026, American Academy of Sleep Medicine
