Board of Review Signatures. Because entering rank advancement into Internet Advancement, either directly or via Scoutbook, and printing the system-generated Unit Advancement Reports typically occur sometime after boards of review are held, obtaining signatures on the report may not be practical. Therefore, after a board of review is held, it is permissible for board members to sign a completed copy of the Unit Advancement Report found at www.scouting.org/forms. This signed report may then be attached to the electronically generated report and submitted to the local council. Guide to Advancement 184.108.40.206
