Green Belt
There is no interaction between you and a work out / sparring partner and there is no one there to correct this interaction.
After all a belt of any level indicates your ability to defend yourself or to fight.
Someone of knowledge and ability has to be there to verify this "quality control" ranking.
After all white belt up to a Master level belt indicates your ability to fight, nothing more, nothing less.
I don't necessarily agree with this. Many people practice martial arts for the fitness and art side of things. Many people do not practice the arts to learn how to 'fight' or 'defend themselves'.
My main issue with these distance learning courses (if they should be called that) is that there is nobody there with you to correct your mistakes, of which there will be many. You cannot possibly earn a rank in a system/style if the techniques are not executed correctly. It all boils down to the application of the techniques within the system, regardless of the students intentions. One must apply the correct technique, in the correct manner to obtain any level of achievement on paper. I am primarily talking about Kata applications as opposed to sparring or drilling partner work, due to the obviousness that one cannot possibly execute a throw or apply an arm lock without the use of a partner.
As I said before, it all comes down to the fact that certificates should 'never' be sold through the mail.
Sure,, there are 'belt factories' that can give out dodgy certificates, maybe there is little that can be done about that. But that still holds a little more credibility than buying a rank through the mail.
Just my 2 pence worth
