If you have an orchid that you would like to submit for judging by the American Orchid Society (AOS), there is an opportunity to do so each month with the Chicago Judging Center. 

The Chicago Judging Center meets on the second Saturday of the month at the Chicago Botanic Garden, 1000 Lake Cook Rd, Glencoe, IL 60022 at 1PM. Judging takes place in the Learning Center, Classroom #6.

In January and July there will be a semi-annual meeting before judging at 9:30AM. In March, monthly judging is done in conjunction with the Illinois Orchid Society Show at the Chicago Botanic Garden Fairchild Room.
