There are no accredited universities or colleges as of 2014 that specialize in tattoo art. However, many schools offer tattooing classes. To become a tattoo artist, there is no degree requirement.
An apprenticeship is usually the best way to acquire the skills necessary to receive a state license. Each state has different requirements, but most states require a written exam as part of the process of being certified as a tattooist. Some states even demand a tattoo artist to complete continuing education credits in order to maintain the license.
A portfolio is generally required for tattoo certification, and art classes are highly recommended before embarking on a tattoo training course.
