The NDSE is offered in nine different specialties, as well as for Dental Sciences. The NDSE is created and conducted by a variety of individuals. The Chief Examiner for each specialty selects the team of examiners, co-ordinates the examination, and ensures that it is fairly conducted. Examiners are selected as a result of their activity and expertise in the specialty and to avoid possible or potential conflict of interest with candidates. Examiners external to the College may be used at the discretion of the Chief Examiner. The Chief Examiner will be part of the Examinations Committee, whenever possible, to chair the Examination and to ensure fair conduct.
