  1. Do you reciprocate with any states if so which ones. Also is it possible to email me an application for the test?

    • Hi Glenn,
      It appears that Arizona does not have any reciprocal agreements. However, they do offer exam waivers with states where the license is “deemed comparable” from another state. So I guess that’s actually broader – it may cover more than just a couple local states the way most reciprocity agreements do.

      You can find info and links to download the form here on the state’s website. I included the overview link because there’s more important info to follow there.
