Interesting Article on Clinical Doctorates
It would seem to me that the clinical doctorate programs in OT and PT could provide RT with an opening. If RT can produce really well prepared M.S. graduates, they may be preferred by employers over clinical doctorates in OT or PT due to being less costly. Also, maintaining the Ph.D. credential for university faculty in RT (and not watering down the quality of scholarship by having those trained as clinical doctorates hired as university faculty as may happen in OT and PT) could result in the strongest university academic programs being in RT.
