We have 3 Bronze tests, 3 Silver and I'm not sure how many gold - after Level 6 Silver you can go into the "competitive" track for the elite dancers. Adults don't, normally (one or two have) of course, and precious few of us test above level 6 Silver.
And at each level we have compulsory dances (2 on each test, and you have to pass both at the same time - no testing one dance at a time as you can in the USA), variation/original dances, free dance and Dance Moves (to be replaced by Skating Moves early next year). At the moment, apart from those who need a full level 6 to go competitive, or to start training to be a judge or a coach, you can take the various strands in isolation. I, for instance, have level 3 Bronze compulsory dances, level 2 Bronze Dance Moves and Level 1 Bronze Free Dance! At the moment - I hope to test Level 4 Silver compulsory dances and Level 3 Bronze dance moves this year, especially the latter.
The compulsory dances are
Level 1 Bronze: Novice Foxtrot, Rhythm Blues
Level 2 Bronze: Dutch Waltz, Canasta Tango
Level 3 Bronze: Golden Skaters' Waltz, Riverside Rhumba
Level 4 Silver: Swing Dance, Fiesta Tango
Level 5 Silver: British Waltz, Foxtrot
Level 6 Silver: Willow Waltz, 14-step
Level 7 Gold: European Waltz, 22-step
and I get a bit lost after that! Blues and Tango and Paso and Starlight & stuff like that, but I get lost in which comes where.
