Some local laws require bartenders to possess alcohol-serving certifications, but these vary from state to state. You don't need a license or certificate to become a bartender in most cases. However, a certification equips you with all the skills and techniques you need to bartend, an excellent option if you have no knowledge or experience in this trade. If you’re keen on acquiring an alcohol-serving license, you can do so by joining a government-approved course and passing the required tests. Remember that a bartending course certification differs from a bartending state license.
