There are one or two organisations which will get your man up to speed, not sure about cost or location.
Do a search on the web for NTTA training.
I am told by VOSA that some are better than others, so check them out carefully before handing over any money – they should be able to put you in touch with recent successful cases.
You can also get test papers on the VOSA website.
