What does the term 'unlicensed personnel' refer to?

The term 'unlicensed personnel' typically refers to individuals who have not obtained a formal professional license to practice in a specific field. In the context of healthcare and physical therapy, this would mean they do not hold any license that formally certifies them to perform duties that require licensure.

Option C suggests that unlicensed personnel are 'persons who are job trained,' which captures a key aspect of what unlicensed personnel can be. They may have received training specific to their job duties but without the certification or professional credentials required for licensure. This training might provide them with the skills needed to assist in certain tasks, but it does not afford them the legal authority to practice independently as a licensed professional would.

In contrast, other options do not accurately define 'unlicensed personnel.' For example, individuals with a temporary permit are still in the process of becoming licensed and thus do not fall into the category of unlicensed personnel. Those working under direct supervision might include licensed professionals or trainees who are still within a supervised learning environment, while individuals with a professional license are definitively not unlicensed, as they have completed the necessary process to obtain their licensure.
