Quality coaches, quality sports. Good coaches make good players. In order to promote coach quality in an ethic perspective, this paper introduces the guidelines of coaches code developed by National Association of Sports and Physical Education, National Federation of State High School Coaches Association, and North Carolina Coaches Association as well as National Federation Interscholastic Coaches Association. It is hoped that ethics can be appreciated by domestic sport coaches so that they may use these guidelines to evaluate themselves to see if they are qualified coaches. In addition, it is also hoped that we may create a proper environment for the development of sportsmanship of young athletes.
