Stanfield's Introduction to the Health Professions Practice Test

Group practice refers to a medical setup where more than one clinician shares facilities, staff, and overhead under a single organizational umbrella, delivering care together as one practice. This contrasts with solo practitioners who operate independently on their own. The other two items are not practice models: one is a certification body for medical specialists, and the other is an accrediting organization for medical schools. So the best descriptor is the arrangement in which multiple physicians collaborate within one practice entity.
