Re: Examination Bowing Etiquette
Ours is an AAA dojo and our test process appears to be the same association-wide. To answer your questions directly, the process is used for both yudansha and kyudansha exams. The person conducting the test selects the uke for the test and most test candidates will face around ten uke in a yudansha test, depending on the number during randori.
In most tests it seems the test administrator will make sure to select uke who have worked with the candidate in preparation of the test as sort of an award or acknowledgement for their extra effort.
