How many courses do I need to take for a diploma of financial planning?

I am trying to find out more about what is required in order to get a diploma of financial planning. Can anyone tell me how many courses I would need to take to get this diploma, and what type of courses they would be? I think that I would like to become a financial planner, and I am trying to find out as much as possible about what would be required of me should I decide to pursue this career. I always like to be able to make well informed decisions, especially about something as important as what career I decide to pursue.
