Does a RPA have to be licensed separately?
No, another license is not necessary because the RPA is an extension of the RT, so a separate license is not necessary in many states. For example, when a physician obtains a license and then becomes a radiologist, another license is not necessary because a radiologist is considered to be an extension of the physician. The same situation applies to a nurse practitioner, because the nurse practitioner is an extension of the nursing license.
