Congratulations ACI Chapter for receiving a 3rd consecutive Outstanding Chapter Award!  Each year, chapters submit an Annual Report Form, which is scored to determine the official Excellent or Outstanding Chapter designations. A large number of points are awarded in the categories of Membership and Meeting Participation.  Without your participation, this Outstanding Chapter designation wouldn't be possible.  So, THANK YOU for your continued support and dedication!
