Like Skip said, the RCDD is the "advanced" degree of BICSI training college.
It is great if you can get some (any) proper cabling training from an organization like BICSI. If you master all cabling install areas, meet the prereq of business and pass the costly exam than you are a viable spokesman and cabling layout designer like Daron Wilson. Many contributors to this forum have on-the-job skills that have served us well for many years; some have taken the additional steps to get the certification and recognition. My hats off to all RCDDs.
