Lillian,
As a former Chief Examiner, I can tell you that you undoubtedly qualify. You need to be familiar with the guidelines in the book they send that lists all the rules; good organizational skills; and a few good people to help you administer it. Most of the candidates are not taking the test for the *first* time, so they will generally be familiar with what they are to do. Plus, they are always mailed ahead of time information that tells them what is expected of them.
You just need to make sure everybody signs in and follows the rules. Being Chief Examiner is a lot easier than it used to be. I hope they already have a site chosen for hosting the test - sometimes that can be a pain.
You also need to find out who is going to reimburse you for site rental - National and state association, or a combination.
