My tips:
1) Give them gimballs until they are at least competent, better expert.
2) Go bounty hunting in a RES to get their rank up. Take the opponents down until they are almost dead and then let the NPC get the kill.
3) Keep your NPC on a tight leash. Use attack my target only for offence and maintain formation to call them back when the target is dead. Never use commands like defend or the others.
