certificate census by location and discipline

This chart shows the number of ARRT credentials held by Registered Technologists (R.T.s) in each state and region. If viewing on desktop, hover over the headers in each column to see full credential name (or view legend at bottom of page). The "Techs" column shows the total number of R.T.s who hold ARRT credentials and the "Certs" column shows the total number of credentials held by those R.T.s.
