Abstract
The International Baccalaureate programs have demonstrated significant growth and popularity in the United States in recent years. A new school dedicated to implementing the Primary Years Program of the International Baccalaureate Organization provided the opportunity for research on the specific actions and qualities of a principal as the Primary Years Program is developed and implemented. This mixed method study of the leadership of the developing Primary Years school leaned heavily on qualitative interviews of key stakeholders of the school to determine a set of key findings for future school leaders of Primary Years Schools. It was concluded that school leaders best serve their school communities as transformational leaders but needed key elements of leader/managers to succeed in the leadership challenge.
