I did the foundation via the ILX e-learning course, and just took the exam a couple of months down the line which I scored highly on. I'm currently considering self funding the practitioner qualification via ILX as I think it will benefit me in terms of making the transition into a dedicated PM role.
My thread from a couple of days ago:

Currently i'm in a technical infrastructure role, and although I manage smallish service improvement projects internally within the team, the process we follow isn't as formalised as it could be as we're too busy doing the 'doing' in most cases.
I applied for an internal PM vacancy very recently, which I was rejected for as I currently do not have the level of PM experience they required. The trouble is, without the opportunity to prove myself within a PM role I'm not going to gain that 'experience'. That's why I'm hoping that gaining the practitioner qualification will make me a more attractive option for such a role in the future... I know that certification does not make up for experience in most cases, but it will certainly benefit me IMO.
