Unlicensed assistive personnel (UAP) is an umbrella term to describe a job class of paraprofessionals who assist individuals with physical disabilities, mental impairments, and other health care needs with their activities of daily living (ADLs) and provide bedside care — including basic nursing procedures — all under the supervision of a Registered Nurse, Licensed Practical Nurse or other health care professional. They provide care for patients in hospitals, residents of nursing facilities, clients in private homes, and others in need of their services such as due to effects of old age. UAPs, by definition, do not hold a license or other mandatory professional requirements for practice, though many hold various certifications. They are collectively categorized under the group "Personal care workers in health services" in the International Standard Classification of Occupations, 2008 revision.
