Yes, there are. Bear in mind, however, that most tattoo artists will recommend an apprenticeship over an online school. I haven't heard much about the idea of tattoo schools, because there is so much to learn about the tattoo business that must be learned on the job and in a studio, preferably with an artist and mentor who has a lot of experience.

Here are some of the tattoo schools advertised online:

Lady Luck Tattoo Studio and School
www.spokane-tattoo-school.com

B A TAttooist
www.tattoocourse.com

Tattoo Body Piercing Institute
www.tattoobodypiercinginstitute.com

Fakir Intensives
www.bodyplay.com/school/index.htm

American Tattooing Institute
www.tatsmart.com

We'd be interested in getting information about these schools from anyone who has attended them, since we have no experience with them or what they offer.
