Hi, Cindy. We aren't artists here. We are mostly collectors. We aren't really the right people to ask.
That aside, most of those tattoo schools are frowned upon because they are purely money spinners. If your daughter wants to be a tattoo artist, she needs to talk to other artists and investigate an apprenticeship in a shop.
For the record, I wouldn't let anyone who comes out of one of those "schools" near me with a tattoo machine.
