This is a naive question, I'm sure.
By googling, I found this East Coast Swing syllabus:

Since I'm new to the concept of a Bronze/Silver/Gold syllabus in dance (I'm aware of syllabi in other fields, so I know what a syllabus is), I'm curious as to who defines this ECS syllabus. Presumably, some dance organization.
Thanks in advance for enlightening this newbie!
