To the OP:
1. Visit the PSO DWAN site. The link I provided you is for Edmonton; in LFWA, this is considered the standard. Prior to briefing your soldier, peruse the options available, such as AVOTP and CEOTP. Determine if he or she qualifies for either of these. Learn what administration will be required by him and by you, such as the correct forms, required transcripts, etc.
2. Counsel the member. Determine if he or she interested in an OT and for what reasons. Determine what trades he or she is interested in. Discuss options.
3. Visit the DGMC DWAN site and research the trade, preferably with the member. Research its entry standards and be cognitive they may not be reflected on the PSO's site (or vice versa); in case of conflict, go with the more stringent requirement. Read the trade's OS; if feasible, provide a print-out for the member's reference. Try to find the QS for this trade. Some, but not all, are available on Documentum. This will give him or her a more solid (theoretical) foundation on the career, its arc and employment and training requirements, which in turn adds weight during his or her PSO interview.
4. Allow the idea to percolate.
5. Assist the member with remaining administration required at his or her and your levels.
6. Wipe hands on pants.
