Can a company offer certification training that is incomplete, then not hire people because they cant pass tests and not pay them for their time and travel to classes?

My wife has been a hairstylist/hairdresser for over 25 years. A company called Davines has openings for trainers and my wife would be awesome at instructing, plus its what she has wanted to do fr a long time.(be an instructor ).
She decided to join the tryouts for an instructor position in tucson for Davines north america. She started the process over a year ago. in that time she has spent thousands of dollars getting from Tucson to where the "classes" were held. At every turn she, as well as the rest of the class, have been expected to give presentations on subjects and procedures that have not been previously described. Theres simply no way they can do well if they have no idea what the subject matter is.
My family is very supportive of my wifes endeavors.
I believe that the company has an obligation to at least give people an opportunity to learn the subject matter before being critiqued. Is it legal for them to "stack the deck", then deny a cerification based on results?
I think its complete fraud and really crappy management.
I believe the company should reimburse my wife for traveling to get a certification, then denying it based on their negligent misrepresentation.
looking forward to a reply.
thank you
