I think you need to send Erel a PM directly on this topic. For starters he has created a wealth of videos which are
free for anyone who wants to learn B4X. There are also people like Klaus who have written exceptional ebooks on B4X coding which are also
free in the forum.
The likelihood is that anyone who wants to teach B4X will use these free resources however their usage terms in terms of teaching other people as a business is something that can be clarified directly by the authors. Questions like is it allowed? If allowed do they get royalties etc, I cant be really sure but I guess because there is an affiliate program that he is running here for b4x, an arrangement of some sort might be needed.
Who gives out the certificates to learners? who accredits those certificates and so forth and things like that? I just commented on a post about certificated on B4X. One programming framework is being taught at schools for example, that would even be nice for B4X, that's
NSBasic
