In sports associations, there are only three grades: bronze medal, silver medal and gold medal.
In the Dance Association, there are nine grades: three bronze medals (1, 2,3), three silver medals (1, 2,3) and three gold medals (1, 2,3).
It seems that primary, intermediate, advanced and gold, silver and copper are not divided in order, they are just two classification methods. Generally speaking, the grading regulations of the same institution are the same.
Generally speaking, children get gold, silver and bronze, and adults can directly take the teacher qualification certificate, which is divided into national A-level Latin dance teachers, B-level Latin dance teachers and C-level Latin dance teachers. There are elementary, intermediate and advanced. But the content of the exam is all those steps, just two categories, I hope it can help you.
