Your characters previous years in training would be included here. The Initiate rank is for the clergy and not the Knights of the Wyrm.
The Knights are the Military arm of the Church if you like. To become a Knight you must indeed go through the initiation ceremony (CDQ). You must apply in writing to a High Justicier and the Divisional Commander(ie Reus is High Justicier in Fort Vehl, Sir Breten Parth is the Divisional Commander for Mistone).
Once formally accepted to attend the initiation you go through the ceremony and are asked to face a number of tests and questions. Based on your answers you may be either; not accepted, accepted as a Squire or accepted as a Knight of the Wyrm (lowest rank apart from squire).
So...after all that..first step is to submit your letter to the relevant authorities, then apply for a cdq with a GM. (In the past when I've done them I have opened up the cdq to others who wish to apply as well and run a group cdq event.) But..any GM can do them as there is a set format to follow for the initiations.
One final note is that if you are not accepted you cannot apply again...(except in exceptional circumstances or for exceptional reasons)
