AMA Class C Referee Training is the foundation of the AMA's referee training program. Class C training covers general rules 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 to review (once it opens, make sure you save it to your computer for reference later), and then take the online test. If you pass, you'll receive an AMA Class C Referee certificate.
An active AMA Membership is required to be an AMA Referee. Visit www.americanmotorcyclist.com to get your membership.

The purpose of this exam is to cover the basic 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.
