No, your right it doesn't but what do you recon the chances are that they will be ??? If you have not come via that route then I would suggest it's very difficult to talk with any authority.
As Fuzzy will no doubt tell you, nothing wrong with the 6129 on its own, every apprentice over the last 7+ years has had to do it, the problem is that unless you can do the 6089 NVQ you are not classed as qualified buy the industry (you could look at the 6089 as a trade skills test i.e. this is the minimum skills that anyone should have before we let them loose on the public), for the reasons already covered.
You can't really think that teaching is the same all over. Does it not make any difference to the learner how good or knowledgeable they are? The times over the years that I have had learners from other places in, to be told "we never covered that" "No they just told us the answers to those exams", "system planning, no we never did any of that they just told us what to put when we went in for the day"
