Once the examination/defense has been setup by the Graduate Program Assistant, the Chair is responsible for following each program's specific process for the complete examination experience (e.g. questioning process from public attendees and examining committee, avoidance of asking own questions, following the time requirements, etc.). This process needs to be followed as precisely as possible to ensure fairness across all students within the program.
However, it is possible for the student and/or advisor to request a modification or accommodation to the process. All requests must be made to the Examination/Defense Chair who is responsible for ensuring that the process is fair to all students. Accommodations are possible as long as these are managed by the Defense/Examination Chair. If you have a defense/examination coming up and would like to discuss an issue related to the process, please discuss this with your Defense/Examination Chair with as much advance notice as possible to allow this person to discuss with relevant others if necessary (e.g. Department Chair, Grad Studies) and/or to arrange the modifications.
