From the AKC website:

Your dog responds well to commands at home and in public, but how would he respond in a farm environment? There’s an easy way to find out: Sign him up for a Farm Dog Certified test.

Open to all breeds of dogs, this test involves your dog performing a series of 12 exercises that are typical for a farm environment such as being in close proximity to livestock (who are always penned to avoid any altercations); jumping and staying on hay/straw bales; walking on unusual terrain; and jumping over logs. There is no herding involved. Instead, the goal is to assess his aptitude as a working farm dog by exhibiting self-control, confidence and trust with you or his handler.
