When you have been approved for the League Excellence Program for the first time you will gain access to a banner to display your level!
You can claim this from the Physical Benefits section in your League Excellence Program dashboard. This dashboard can be located underneath your organization dropdown on your USA Football Dashboard.
After receiving a banner the first year in the League Excellence Program, your organization will only receive a Bronze, SIlver, or Gold sticker in subsequent years. The stickers are designed to peal off and put onto the banner.
