I feel as if the licensed Dentist has authorized and approved a DA I’s capability to become a DA II there should be no problem. Colleges teach basics and if a DA I has the opportunity to do on the job training, seeing and learning in the real world; I say go for it! The licensed Dentist should be the ones imputing more because they will be the ones allowing and training. Its a great opportunity and if the licensed dentist entrusts that person they know they will be liable, so they know who to and who not to entrust with this certification.
