The CAA have had the JAA CPL exams available for over a year, the problem is that there was only one CPL course available and the company ceased trading so there have been no candidates to take the exams.
The CPL exams are actually extracted from the ATPL syllabus question bank for which I am told there are training objectives.
I also hear that a number of CPL courses are likely to appear in the new year so watch the adds.
