Hi Jennifersd86!
If your proctor is now your boss, that won't be an issue. The only stipulation would be if you were your proctor's boss, but in the scenario you described, you will be allowed to continue to use your current proctor for your exams.
For additional information, please be sure to see the Proctor Exam FAQ and the Veterinary Technician Proctor Exam F.A.Q. Thanks, and good luck with your studies!
