Leadership is defined as a visionary activity that aims at discerning the values of an organization, making these values exemplary, and inspiring, even transforming the people in the organization, so as to feel and act in the same way in order to achieve predetermined objectives. Even though there is no specific model of successful leadership, the main schools of thought attempt to identify effective leaders’ characteristics and the organization factors that affect one's ability to lead, and study the leader's associates group characteristics and how they affect his efficiency. By means of a questionnaire based on the following axes: leadership conditions, the leader’s personality traits, the potential leader’s skills and competencies, leadership styles, actions for goal achievement and preparation for a future leader, the current study examines the validity and reliability of an instrument (a structural equation model), which records the influential factors on the axis of actions for goal achievement and preparation for a future education leader. More specifically, it evaluates construct validity by estimating both convergent and discriminate validity, while evaluating the internal consistency of the instrument itself, and estimates how the instrument determines the reasonable relations among the latent factors mentioned above, and how it describes the reasonable results and assigns the quality of data fit within it. The specific instrument can be used by researchers to evaluate the effect of these parameters on effective leadership, and by candidate educators or class teachers-leaders to be aware of the changing role of leadership factors in order to be well-prepared and effective.
