About the RMJC


The Rocky Mountain Judging Center was established by the American Orchid Society (AOS) in 1990. It covers the largest geographical area of any AOS Judging Center. The region includes the States Colorado, Wyoming, Montana, New Mexico and Utah. Judges from the region travel to the Colorado judging center each month and to AOS sanctioned orchid shows in this region. Judges are typically expected to judge outside their region every year – places like Omaha and Oklahoma City are favorite “nearby” destinations.

The American Orchid Society is the authority for orchid judging in the United States. The AOS Judging Committee is responsible for maintaining standards of awards for flower quality, for orchid culture and for plants of botanical or horticultural merit. The committee governs and certifies approximately 675 judges, and has established 35 Regional Judging Centers. Judging Centers provide a forum for orchids to be judged in addition to judging opportunities at AOS sanctioned orchid shows. The centers also train student judges and conduct seminars to educate their members and the public on a variety of topics. The AOS, which establishes rules and regulations for orchid judging, publishes them in the current edition of the American Orchid Society Handbook of Judging and Exhibition.

If you are interested in observing the judging process, learning about orchid judging or submitting an orchid for consideration of an award, you are cordially invited to attend the meetings of the Judging Center.
