Understanding Yourself and Others - DISC was a free course developed by Sandler and Crystal Knows. It was always provided at no additional cost in Sandler Online.
We no longer have client-facing $0/free channels in the new LMS, so these have been added as resources available in all the other paid channels.
You can access by going to the Content tab in the channel that's paid for > Category > Understanding Yourself and Others - DISC.
You can also search for "DISC" in the search bar.
Path: Home>Pick a Channel, once channel opens choose Content
From here search DISC( enroll if not already enrolled or choose to play).
