Anakin received his scar at the hands of Asajj Ventress in the comic Star Wars: Republic #71 - The Dreadnaughts of Rendili, Part Three
. He was knighted in Chapter 21 of the Clone Wars
The Jedi trials
article on Wookiepedia lists the various trials of the old Jedi Order, and notes where we've already seen Anakin go through them:
- Trial of Bravery = experience due to fighting in the Clone Wars
- Trial of the Flesh = loss of his forearm to Count Dooku
- Trial of the Spirit = vision of a possible future as Vader (Clone Wars Chapter 24)
That leaves only two trials that we haven't seen. The first of these - the Trial of Skill - could easily be considered as passed through his natural affinity with a lightsaber or with Force abilities, or in the same way that Bravery was considered to be fulfilled. The Trial of Insight might have been considered fulfilled by Skywalker's leadership of clone troopers (strategy in battle, etc.).
