Are there any staging courses for CEs out there?

As important as staging is, why don't Realtor associations offer staging courses for credit? I thought that if any state would offer a staging course designation, it would be California. I googled it and all I came up with is a course that is offered for no credit. I feel that one of the biggest obstacles to getting Realtors on board with staging is their lack of exposure to staging and the benefits of staging. If they had courses on staging for credit, I am sure that many Realtors would be interested in them. If they understand the benefits and the ways of presenting the subject to their clients, I believe it would mean more business for everyone.
