What must candidates provide to request special accommodations?

To request special accommodations, candidates must provide medical documentation and a completed form. This requirement is in place to ensure that any accommodations needed are justified based on the candidate's specific circumstances. Medical documentation serves as proof of the condition that necessitates the accommodation, while the completed form helps to detail the specific accommodations being requested.

Providing a letter from a friend, making a verbal request, or paying an extra fee does not align with standardized procedures for formal requests for accommodations. Such procedures are designed to maintain fairness and ensure that all requests are properly vetted and documented to meet the needs of candidates with disabilities or other qualifying conditions. Hence, the correct response embodies the necessary formalities required to facilitate appropriate support during the certification process.
