In the United States and worldwide, the process for becoming a polysomnography technician or technologist is primarily either on-the-job or certificate based.[1] There are associate level programs offered by for-profit schools that award a degree in polysomnography technology in the United States, though not necessary to attain employment with the same title.[2] After an education program or adequate on-the-job training is complete, the student is eligible for credentialing by the Board of Registered Polysomnographic Technologists (BRPT), a non-profit credentialing agency based in the United States but serving polysomnographers worldwide. The BRPT maintains credentialing for over 35 countries including Canada and the United States as well as over 17,000 individuals working in the industry.[3]
