I have been the only Internal Auditor at my bank for the last ten years. The bank has now grown to the point of the need for more help for me. Management has chosen another employee who works within the bank to work part time with me. I am struggling with setting up my plan to include another person. Anyone have any suggestions?

One of the easiest ways to integrate them into the plan and give them a real sense of accomplishment is to assign the "required" audits to them, e.g. ACH, BSA. I know you have a catalog of prior year's work to serve as a guide which will give both of you comfort that your PT new staff won't go too far off track and will help you accomplish a portion of your audit calendar.
Congratulations on getting more staff.
