I have a sonographer who failed the RVT examination, did the ARRT exam and
>passed with flying colors....over 90% correct responses.
Personally, I find it disheartening that after failing the RVT exam that your sonographer would not study harder and "slay the dragon" instead of moving on to the ARRT exam. What message does that send? The ARDMS, like it or not, is the "Gold Standard" of sonography professionals. If "just being credentialed" is one's goal....well....to each his/her own.
my 2 cents (if that)
