No person shall participate in a resident physician assistant program until he has received a license or temporary permit issued pursuant to section 20-12b or a training permit issued by the department. The training permit shall be issued solely for purposes of participation in postgraduate education as a resident physician assistant in a short-term hospital, as defined in the regulations of Connecticut state agencies and licensed pursuant to subsection (a) of section 19a-491, that provides a postgraduate medical education program accredited by the Accreditation Council for Graduate Medical Education. No person shall receive a training permit until a statement has been filed with the department on his behalf by the hospital administrator certifying that such person is to be appointed a resident physician assistant in such hospital and that he has satisfied the requirements of subdivisions (1), (2) and (5) of subsection (a) of section 20-12b. Such training permit shall authorize the holder to participate in clinical educational activities only when the supervising physician is physically present on the premises and is immediately available to the physician assistant when needed, but shall not authorize the holder to prescribe or dispense drugs.
