While vision-based leadership, frequently referred to as transformational leadership in the education literature, is widely regarded as critical to successful organization transformation, little research has been conducted into the relationship between vision-based leadership and public school performance in Thailand. Derived from substantial literature, a model is proposed to investigate if vision attributes (brevity, clarity, future orientation, stability, challenge, abstractness, and desirability or ability to inspire) and content (relating to teacher and student satisfaction, and efficiency) are associated with higher public school performance, while taking into account Principal, Teacher, & Organizational Factors. Future research directions and managerial implications are also discussed. Copyright 2005 by Education Research Institute.
