Judging Centers (see judging centers below) The AOS's judging system is comprised of 27 Centers comprising 34 sites throughout the United States and Canada. These Centers provide opportunities to have plants judged on specified monthly dates. The Centers also provide judging service to AOS-sanctioned shows here and abroad. Center activities are open to visitors who wish to see the judging process in operation or bring their plants to be evaluated. Meeting dates, times, places and contact information are published each month in Orchids magazine as well as on our Events listing. Orchid plants may be submitted for judging using the following guidelines. All orchid plants or cut flowers submitted at a monthly judging session are candidates for an award. Plants must be entered in the most presentable condition possible. Judging Center Plant Entry Plants may be entered by the owner in person or by someone else on his/her behalf. The exhibitor completes a single sheet entry form for each plant entered for judging. After an entry number is assigned and annotated on the form by the Judging Center Clerk, the exhibitor places the entry form with the plant on the display table.
