I've read before (not in EU since I don't like that stuff and I don't read books) that there are a series of different tests. Some on lightsaber skills, some on Force powers, some on just normal mental and physical things, and that there was some sort of code to recite or something. I assume that it is very intricate, involving lots of things, but when I wrote a story of my own, the trials consisted of this:
1. Blocking blaster bolts with a lightsaber
2. Piloting a ship
3. Force powers- all of them, even the ones some of you might not know
4. Blaster training
5. Hand to hand combat
6. Obstacle course with a combination of everything
7. Lightsaber duel (non-lethal lightsabers) with a Jedi Master
Don't wanna brag but I like that a lot, I'd love for that to be considered canon...too bad Lucas doesn't read this site.
