During Class:
When the instructor bows to the class, bow in return to the instructor.
After the warm-up exercises and after the demonstration of a technique, bow first to the instructor and then to your partner before beginning your practice.
Try not to be late for class. If you are late, kneel by the side of the mat and wait until the instructor invites you to join the class. Thank the instructor with a bow and join the class. If you have missed the warm ups, take time to stretch out at the back of the mat. Then approach any group of students and ask to join them.
When the instructor determines that it is time to stop or change techniques, the instructor will clap or announce it verbally. At that time, bow to your partner and move quickly and quietly to the edge of the mat and observe the demonstration from seiza (a kneeling position where you sit on your heels).
If the instructor stops to provide clarification concerning a technique, move to a place that is safely out of the way and observe while sitting in seiza . After the correction, bow to the instructor, then to your partner, and resume practice.
Should you need to fix your gi during class, first bow to your partner to indicate the interruption in practice. Then face away from the mat while straightening your gi . When you are done face your partner and indicate your readiness with a bow.
Once class has started, never leave or re-enter the mat area without asking the instructor.
Always report any injury to the instructor.
There is no shame in having to stop to catch your breath. Sit in seiza or cross-legged at the edge of the mat. (Never lean on walls or columns in the dojo.) Your partner can join another pair until you are ready to continue.
At the the end of class, straighten your gi and line up in an orderly row as in the beginning of class.Bow to the instructor as the instructor bows to you.
