I think this is absolutely necessary.  There is no reason why an experienced, trained, unlicensed assistant cannot place an IV catheter when necessary.  There are not enough licensed technicians available or working for it to be practical to only have licensed technicians place IV catheters.  Many practices don't even have a licensed tech on staff.  Having worked in other states, many unlicensed techs had more experience and were better at placing IVC than myself.
