In molti stati, per avere la licenza di tatuatore, è necessario completare un corso sugli agenti a trasmissione ematica, oltre ad altri requisiti. Chiaramente, dato il contesto fornito, la persona in questione ha completato il corso ma gli manca qualche altro requisito non meglio specificato.
Non bisogna quindi semplificare la dicitura, perché i titoli dei corsi hanno sempre diciture professionali.

What Tattoo Certifications Will I Need?
While success in the tattoo industry is based on skill, there is actually no requirement to prove oneself as a talented artist or stellar business owner in order to obtain a license. Instead, certification is mostly focused on compliance with standard safety measures to protect potential customers.

The Bloodborne Pathogens training course is a common prerequisite that nearly all states require in order to obtain a tattoo license. It must be offered by a legitimate organization that provides certification, such as the American Red Cross Association

How to Become a Tattoo Artist: Career Guide



Learn the sequential steps to becoming a tattoo artist. Research training options, necessary experience and licensure information for starting a career in tattooing.

Step 1: Compile a Portfolio

Step 2: Complete an Apprenticeship
The APT recommends an apprenticeship of at least three years.

Step 3: Take Tattoo Artist Education Courses
Many skills needed for a successful career as a tattoo artist can be learned from an apprenticeship with a knowledgeable artist, but some health departments and other state and local regulatory agencies also require classroom experience. Seminars in disease prevention and skin diseases/infections and training in blood-borne pathogen prevention may be required for licensing.

Step 4: Get a License
Most states require licensure for tattoo artists; however, requirements vary by state. Oregon, for example, requires licensees to complete a minimum of 360 hours of training under an approved artist as well as 50 tattoos. A written exam and a skills assessment also are typically necessary for licensing.

Step 5: Continue Education for Advancement
