Well, there are syllabus steps allowed in Gold that aren't allowed in Silver, for instance you can dance fallaways in Gold Standard but not in Silver. As far as technique goes, the higher you go in the levels the more is expected of you in terms of posture, movement, connection, balance, speed, stretch, and so on. It's not like "Gold dancers are taught technique X but Silver dancers are only given Y." A good teacher should be cultivating the desired technique in you regardless of level. It is true that Gold dancers tend to dance better than Silver or Bronze dancers, but that's only because Gold dancers tend to have been dancing longer and so have more experience and training. But that's not an absolute. There are no absolutes. You'll run into people who announce they are Gold dancers but who can't lead a waltz basic to save their lives, and you'll find Bronze dancers who have beautiful timing and clear leads. Honestly, declared level doesn't matter -- what matters socially is how well you lead and follow a variety of partners from all levels, and what matters competitively is that you feel good about what you are doing and what your results are.
