Club dancers are sometimes very rhythmical with nice body action.
What is missing are the partnering skills that allow them to dance with the good dancers. Also we have standardized names for the skills, elements and patterns. In level 2 we don't teach those things, we just say the name and expect you do what we request. Having the terminology makes everything quicker and easier. Every school has a different system for determining the levels of the students and classes.
