If you have not got a level five qualification you may be forgiven for some confusion. Some people advise that you should hurry up and get it, others say wait and see. If you don't want to pick through the technical arguments, try this one instead:
It depends on your attitude to training. If you think that all the training in getting level five is going to add very little, then you may place more weight on the value of delay. But if you think that they training is likely to be valuable, then even if the precise requirements change and you have to do some more training again later, you will get value, so go ahead, do level five.
I suspect the learning is never wasted.
