After the initial trial period has ended, we require all members to wear proper uniform (WTK T-shirt, pants and shoes) during training, whether in classes or at seminars.  There are no belts or badges.  Experience and rank is denoted by the color of your WTK T-Shirt, which shows your current stage of training.  There are two (4) different colors.  The white shirt is for Beginner Levels 1-4, the gray shirt is for Intermediate Levels 5-8, the navy shirt is for Advanced Levels 9-12, and the black shirt is for Instructor Levels.
