Want the idiot-proof answer? People PAY for this! That's why. DO YOU GET IT? Would you pay someone for flight lessons if they could not prove to you they are a certified flight instructor? DO YOU GET IT NOW?
As for the credentials most of you ask for, I feel as students yourself the manner in which it was asked was more pessimistic than optimistic. Yes we all have questions and would like it to be answered, but ask yourself if you deserve an answer first, coz in life others owe you nothing.other schools and forms of MA might upon request give their credentials without hassle but why do you deserve to know would be my main question.
Really? So Macdonalds will not sell you a Franchise if you come up with the money? Areyou trying to be super-naive?
above is a link to which the NMA has a block, this means that in SA only the institutions listed below can provide a student with national colours,so in all the NMA is registered with SASCOC,ISKA, MA & GC and WAKO. I'm sure these bodies will not allow affiliation or registration if the head instructor does not have the required credentials.
