You don’t need to register for both the 8 hour pre-registration security course, and 16 hour on-the-job training at the same time. However, the 16 hour course must be taken within 90 days of your first employment, so it makes sense to take care of it before you get a a regular job. Plus, Knight Training Institute offers seasonal discounts on both 8 and 16 hour courses when you register at the same time, take advantage!
