AMA Class B Referee Training is a continuation of the AMA's referee training program. If you have successfully completed the Class C Referee exam, this is the next step. Class B training is discipline specific for MX, Track and Off-Road racing. To begin, make sure you have a current copy of the AMA Rulebook and download the study guide for your discipline to review (once it opens, make sure you save it to your computer for reference later), and then take the corresponding online test. If you pass, you'll receive an AMA Class B Referee certificate for that discipline.

The purpose of this exam is to cover the core Class B Off-Road Referee knowledge areas for referring AMA Sanctioned races. A passing score is 75% (19 out of 25 questions).

Please enter your contact information as well as your AMA #. This information is required for our Test Administrator to identify who you are as well as send certificates to you upon passing.

If you need assistance or have questions while taking this test, please contact: Melody Tucker at 614-856-1900 x1287 or mtucker@ama-cycle.org
