The National "C" License course addresses the challenges of working with 15-18 year-old players and represents a substantial and significant commitment to the profession of coaching. Candidates think about, discuss, and recognize the recurring concepts or themes that exist in soccer; identify the roles and responsibilities of players; and assess how the principles of play impact the coaching process. A primary emphasis in the National ‘C’ License course is the close relationship between technique and tactics. During the course, coaches practice organizing, developing and implementing appropriate training sessions to correct and reinforce the demands of the game. The “C” License requires seven days of onsite instruction, 6-8 weeks of assignments, and three days of onsite assessment.
