To be able to breed tribbles within the Federation, it is required to have a license and be a member of the United Federation Tribble Show and Breeder's Association, or one of the connected organizations.

The written test includes the following topics:

Keep in mind that the number of tribble breeders is kept very limited due to the enormous fertility of the tribble.
