Certification programs are more about demonstrating your competency than about learning how to manage. Consider this: PMP and IPMA certification takes you through a process guide and a comprehensive examination that you can easily enough learn in a few weeks. I always recommend learning the bodies of knowledge, so long as you are fully aware of what you're getting... But be aware of what you are actually getting. Here are a few things that your certification program is definitely not going to teach you.
I'm frequently asked what I think of certifications such as the Project Management Institute's PMP, or its other programs. The PMI's Project Management Body of Knowledge (PMBOK) represents a strong reference guide, and one that I turn to when appropriate as a process guide — but its very strength as a reference text also makes it a poor companion for someone looking for a comprehensive project management methodology. There's a host of information you won't get in school (not even from a top tier management school, let alone a certification program you can cram for in less than two weeks).
Most managers today have blinders on when it comes to solving the problems of complex projects: They are lost among the trees, and can’t see the forest for what it really is. Too many project managers are focused on the day-to-day problems of the project and have lost sight of their overall strategy. So, with KPMG telling us that nearly 70% of projects are failing to meet their goals, what's the real solution? What's the one thing that's going to make the most difference?
