Promotions to partner appear to be a bit of a black box, even to those in the process themselves. I expect most people's information on this subject to be based at least in part on rumour/3rd hand info.However, it is a fact that there has been at least one promotion from AP to P that I can think of in recent years. They do not appear to be common and certainly not the norm.I'm told...that promotion from Director to AP is in most cases not a choice made by the individual. In these instances the path to P is extremely unlikely.However, if recruited at AP, I would expect there to be greater opportunity to progress to P with strong performance.
