This case report presents the process by which a beginner coach practiced across seven months (214 days), from April to October 2014. The subjects were forty-seven male and female college and graduate students in the jump team of a university athletics team; the author was the assistant coach of that team. The results of the learning process of the beginner coach are examined in this case report as follows.
    In April, the beginner coach felt primarily anxiety, as the coach had only begun coaching. However, we overcame the various problems encountered in the process of coaching practice by reflecting on and thinking about a series of processes in the training plan, training practice, and training assessment. By building a relationship of trust with the athletes, the beginner coach began to be asked coaching questions more often by the players. Therefore, beginner coach became more confident about coaching. In order to transform into a coach who can respond to every question and situation, a beginner coach must practice and reflect on the coaching process every day; it is essential to continually repeat this series of processes. In order to share the knowledge that comes from coaching practice and to co-create a learning group of professionals who coach, it is important for the coaches leave records on the coaching practice. Finally, it was understood that coaching requires considerable time and resources, and even beginner coaches face challenging economic burdens, such as tour costs while coaching.
