Can I ask job applicants to demonstrate how they would perform the job?

Applicants can be asked to describe or demonstrate how they would perform any or all job functions, as long as all applicants in the job category are asked to do this. Applicants who need a reasonable accommodation of a disability to do a job demonstration must be provided a reasonable accommodation or allowed to simply describe how he or she would perform the job function.

Even if other applicants aren't asked to do so, a particular applicant may be asked to describe or demonstrate how he or she would perform a job function. But you can ask only when it is reasonable for you to believe that the applicant will not be able to perform a job function because of a known disability. You may know about a disability either because it is obvious, like when the applicant is in a wheelchair or missing a limb, or because the applicant has voluntarily disclosed that he or she has a hidden disability.
