In my head, the elements of proficiency are:
1) Knowledge of the figures and their transitions
2) Ability to lead/follow in rhythm
3) Technique that characterizes the dance
With ballroom syllabus it's easy because there are categories of figure lists which bronze-level people must know. And the books.
It's not so easy with the club dances. What is "intermediate" salsa to you? or "intermediate" lindyhop? How much ECS should you know before you start WCS, or do you need any of it? The skill set for these dances is hard to specifically define as no one has ever wanted to standardize them. That is partly good because you cannot be constrained by what you know... but it drives some of us who take those lessons nuts. That's where we get random people who think they know basics in ECS taking lindy; they think they know, but they don't really know.
