Administration of licensing laws differs from state to state. Some require that
a state application be submitted prior to working in the state, while others require
only ARRT certification and registration results. ARRT refers questions about state licensing to
the individual state licensing authorities. View a list of state licensing agency contacts.

who are not eligible for ARRT certification and registration and apply only to the state. Learn more
