Re: Examination Bowing Etiquette
"After being called out by the exam administrator (or panel) one issues an audible acknowledgement (hi) and moves into the center of the mat. Then after a partner is called out, one completes a formal seated bow first to the Shomen, next to the administrator(s) and finally to your partner. At the conclusion of the examination the bowing order is reversed, first to your partner, then the administrator(s) and finally to the Shomen."
that's correct. at some dojos over the years they didn't reverse it at the conclusion, but now it's become pretty standardized. so you bow 1st and last to the Shomen
