Narrative:

I was conducting OJT on stn/stv; we had just gotten the briefing. There was a small single piston holding south of kizer at 3;000 ft and the previous controller had climbed a twin turboprop to 3;000 ft and turned on the north downwind for the ILS 9L. This created a conflict between the twin turboprop and single piston; I pointed this out immediately to my trainee. The trainee turned the aircraft but waited to descend. This caused them to come closer than 3 miles. Well I teach my OJT's not climb to 3;000 ft on the downwind if holding at this holding fix. If you get this handed to you it may take precise vectors to avoid the holder and possible traffic on the ILS. You can always have the single piston/holding traffic turn north to the fix early due to traffic. I've been told to give my trainee a long leash but in this case I've learned that leash was to long and I needed to take over.
