You are not going to get a sympathetic hearing on this forum for how much more valuable good salesmen are than good dancers. I'm not sure if it's a language thing or what. "Accolades"? Did they win open level events in independent comps? Or did they get an "attaboy" at a franchise-only comp? Ballroom dance is a field that has only one credential to authenticate one's dance skill, and that is winning comps. The various teaching certifications prove that one has passed a test on particular dance syllabi. Does a beginner need to learn from a Blackpool Finalist? Probably not. But a beginner is not going to be able to distinguish the quality of a teacher by just looking. Credentials, whether from winning comps, being qualified to judge comps, or teaching certifications give some assurance.
