Should CIN TTT (Live or On-demand) classified as

a) Live Webinar
b) Training course

For the purpose of re-certification CE credits?

Thanks for your attention to this matter
Neither. Like Rick said, they are Preparation Courses for Trainers, that want and Update / Intro about the Course Content and how it my be presented.
That may also depend on the TTT how deep it goes. But the TTT does not prepare so well for an Exam nor is a complete Course. So its Intent is for Trainers. Not students.
