Judging Centers (see judging centers below) The AOS's judging system comprises 27 Judging Center locations and 9 additional sites where judging takes place throughout the United States and Canada. These Centers provide opportunities for the public to have plants judged on specified monthly dates. The Centers also provide judging service to AOS-sanctioned shows in the US 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 listed below as well as on our website calendar events listing. Orchid plants may be submitted for judging using the following guidelines. All blooming orchid plants or cut flowers submitted at a monthly judging session are candidates for an award. Candidates should be entered in the most presentable condition possible. Candidates may be entered by the owner in person or by another attendee on his/her behalf. The exhibitor or proxy completes a single sheet entry form for each plant entered for judging. As an alternative option when it is not possible to bring the blooming plant to the center location for judging, the entire flowering inflorescence can be mailed to the contact listed for the judging center to have it judged during a monthly judging. If mailing an entry for judging, please contact the center chair first to confirm the mailing address.
