Welcome to the exciting world of Respiratory Care and Polysomnography! The Department of Respiratory Care at Texas State University-San Marcos is one of the largest bachelor degree programs affiliated with a university in the nation with over 133 fulltime Respiratory Care majors, 6 fulltime faculty and 12 adjunct clinical faculty. Our goal is to assist you in successful becoming a Registered Respiratory Therapist (RRT) or a Registered Polysomnographic Technologist (RPSGT).

The Polysomnography Course of Studies is offered at the undergraduate and at the post-baccalaureate levels. The 18-hour course of studies are offered each fall & spring to qualify individuals to immediately sit for the national PSG board exam upon completion the paid internship requirement. Students who are admitted to the Interdisciplinary Studies program may petition up to 15 post graduate hours from the polysomnography program for degree credit toward a Masters of Science in Interdisciplinary Studies (MSIS) degree at Texas State.
