Hardly thread sniping, I am almost certain you cannot take on an apprentice if you yourself are an apprentice. If you two were to roleplay together, you could both achieve the rank of knight, through self training. Eg, sparring together and discussing the intricacies of the force with one and another and so on and so forth.
The ranks exist for a reason, and an apprentice/acolyte/padawan/initiate is generally someone with a level in the force equal to their rank; low. Generally, as well, a knight will always be stronger than an apprentice, and a master will always be stronger than a knight -- at least in terms of raw power. Sure they are defeated by lower ranks from time to time, but that's usually because of either great writing or as a plot device.
Sorry if I ruffled some feathers, I suggest you contact an RPJ to confirm that you can in fact take on an apprentice before you actually do so, as I am not 100% sure. Be a shame if you did all these great training threads together and then his promotion to Knight was denied because you weren't one yourself! :/
