I am the chairperson for the Dept.of Health Services Advisory Committee for Special Licensing in Arizona. Our state has moved forward on seperate licences for Audiologists and hearing aid dispensers. Audiologists that dispense are licensed based on graduating from an accredited institution and do not have to take the hearing aid exam to dispense.  It was passed several years ago and has worked well in Arizona.  In fact, Audiologists and hearing aid dealers support each other on many issues.
