Here you go applesmom.. http://www.nk9dta.com/selecting_trainer.aspx It should answer most of your questions. This is one of several schools that once you are certified, you can then get licensed in your own state. Licensing requires you to also be bonded ( like a licensed electrician etc would be.) You can not be get a license without a certification of an accredited school. This also explains the difference from a certified trainer and and a licensed one. Neither would be fine but licensed means you are bonded, subject to state laws and reported to the Better Business Bureau etc.
