Can you get a tattoo license with out going to school for it?

You can't get anything without learning how to do it first then putting in the time doing it under supervision. Would you see a doctor who hasn't gone to school and received his/he certification? Well how do you expect people to trust you if you don't know what you are doing? Besides that all health units and city licensing agencies will check your back round to make sure you know what you are doing before they will issue you a license.
