Basically there are two steps needed in order to register your proctor.
1. Locate a suitable individual/organization who is willing and able to act as your proctor.
2. Have them complete and submit the Online Agreement Form: Proctor Application
This form is NOT to be filled out by you as the student. The proctor must fill it out from the terminal you will be using to complete your exam.
You will both receive a confirmation email when your application has been reviewed, usually within one business day.
