I have been following this discussion for some time now with great interest. I have recently become an accredited Assessor for renewals Level 4 in Germany. The German LBA is taking the whole thing very seriously and, if the exams are all done the way they should be and the way I learned to do them, then they could be difficult indeed for some people. But I'm afraid there will be lots of "cheating".
As an American myself, I was able to obtain the Level 6.
2close, it would be interesting to continue discussing this. At the moment I'm at the office and need to get to work
