The application asks for the state(s) I have been licensed in and asks for the basis of licensure. What does that mean? What if I'm licensed in more than one state? Do you need verification from all states I have ever held a license in?

In the basis of licensure box on the application, you need to indicate whether you became licensed in that state by Exam or by Endorsement.

We need verification from all states where you have ever held a license. This is to ensure there have not been any disciplinary actions or suspensions and to ensure that your current license is in good standing.
