My 2 cents....
I would tend to agree with Jonathon on this one when he says dance knowledge matters more than syllabus knowledge. I really wouldn't sweat it if my teacher didn't know an american rhythm pattern. For one thing, there must be a dozen different syllabus out there (If the teacher was certified in a particular sylabus, it may be a different story). For another, It has been my experience that knowledge of the Silver American Style syllabus does not always correlate to dancing ability. I used to take American Rhythm lessons with a great talented International Latin dancer. She was in the midst of an illustrious career and was enjoying great success as an international latin dancer. She won many titles and was in great demand as a performer and a coach. However, she didn't know the American Rhythm syllabus at the silver level.
Every so often, she would stop in the middle of our lesson to review the pattern with a fellow instructor because she didn't know the pattern herself! However, I never really felt worried because when she came back, she would know the pattern and would use it to illustrate basic technique. She would know the intricacies and be able to explain what made the pattern work and what were the key essential elements I needed to know in order to lead and dance it well. Later, we would revisit the pattern after I had it down cold and add her unique take on styling and even made it look different than other teachers teaching the same pattern :!: .
In contrast, I know of some very experienced teachers who knew the entirety of the same American style syllabus but couldn't dance a lick much less explain how they worked. Consequently this was reflected in their students. Yes, they could pass an exam, but they really didn't know how to dance. The irony was that lessons with both teachers cost the same! :shock:
In American style, I'm more prone to giving a good dancer a break when it comes to syllabus knowledge. I think I would need better reasons to do the same with International style.
Jenn, I really wouldn't sweat it if you have confidence in your teacher's dance ability and knowledge. If you don't, then that may be a different story altogether.
