It is a participant’s choice to disclose (or not disclose) a disability. Once a participant has been accepted, you can confidentially inquire with the participant to determine whether he or she may need accommodations during the program related to mental or physical disabilities. In making disability-related inquiries, you might want to include disability professionals in the conversation too. The individual is protected by the non-discrimination laws if they are perceived as having a disability (even if they did not tell you).
When making choices about accepting or denying an applicant, disability information should be disregarded in the same way as any other non-discrimination status such as religion, ethnicity, or sexual orientation.
Many exchange advisors assume that accommodating people with disabilities in their programs will be prohibitively expensive. In fact, many accommodations are cost-free or quite inexpensive. The key to finding low-cost solutions is to foster open communication with the exchange participant and to think broadly about the possibilities and resources available to the organization and the participant.
