my dqc card + tacho ?
my license is still being processed with dvla as i passed recently? and i cant seem to find my passport
It used to be that the physical licence was needed but not sure if that is still the case as all your licence info can be seen online …
Best way would be to check with the provider of the training as it will be down to what they want from you to some extent.

That’s say any of the documents for identity proof. 
I have just competed CPC refresher. My license was with DVLA to add my new category and as it was due to renewal as well it took time as clearly DVLA has problem to do two things at ones.
Bottom line is that I have called my course provider and there were happy with my license summary printout from website and my current cpc card.

Licence in your hand is not required, as long as you know your driver number.
