I know it can be done, but in the Architect Associate exam did not find the option. I am planning to take the Pro next week, and would appreciate any tip of where to find the option when booking the exam.
I’m going from memory here and haven’t requested an extention myself, but when you go into the Certification Portal (certmetrics.com), there should be four buttons on the right. The top button says "Request Exam Accommodations". From there, you click another putting and get a dropdown. Somewhere on that dropdown is "ESL 30+ minutes" or something to that effect.
Once you’ve done that and get approval, I think you can proceed to book your exams if you haven’t already.
