Earning credentials Using The PostPrimary Pathway

After earning your first credential from ARRT (or in certain cases from another organization), pursuing a second credential using the postprimary pathway is a great way to enhance your professional development. (Note—this is different from pursuing a second credential using the primary pathway.)
