As Keith and others have said in many posts :
I repeat what I have said in other posts - CIPD qualification levels certifY the possession of technical knowkledge, and not the demonstrated ability to use it in real life situations, that is done by the Member and Fellow membership level IMHO. It is technically possible to obtain a level 7 qualification however this alone does not guarantee the person has the proven track record operating at senior and strategic levels to be able to obtain the grade of Fellow or even Member.
Finally, I would reword Keith's comment about age and put it in terms of experience - getting a senior job usually requires 10-15 years of applied experience in jobs where responsibilities have increased over time. I have seen people enter the profession at 40+, and take a fast track to the top on the basis of the skills mentioned above, whilst relying on the heavy technical knowledge of their teams. The best R&D directors are rarely the "best" tecnical experts - their job is to coordinate, prioritise and manage others who handle the techy things. I also had the privilege of working with the CFO of a £90bn business of 200.000+ people in 67 countries; he became CFO at 42 and believe me, his technical skills were less and less important as he moved up the ladder.
