This study was designed to develop a teacher leadership styles scale. McGregor’s X and Y Theories were accepted as the therotical base for the development of the scale. As it is clearly known, the roots of McGregor’s X and Y Theories base on the behaivourist leadership theory. McGregor’s X and Y Theories have a bipolar structure. According to McGregor’s X and Y Theories the leadership behaivour of those who made Theory X would be autocratic and directive, while those with Theory Y would be democratic and participative. The main reason for using McGregor’s X and Y Theories for the development of the scale is that leaders assumptions about the behaivours of people are one of the major predictors of their behaivour. Depending on this assumption it is thought that teachers’ perceptions about student behaivour would play an important role to lead their leadership styles. During the development phases of the scale, expert view and item rest technique were used for validity and internal cosistency (cronbach α ) was found for relaibility. The data were collected from 137 high school teachers from different schools and fields. In the first phase, 30 statements (items) were collected basing on the expert views, and related literature. Item rest analysis were performed and items loaded 0,40 and above were kept for the last form of the scale. The scale consisted of 17 items after these analysis. The internal consistency of the scale was found as α=0,88 for the scale. Teacher leadership style scale is found to be valid and reliable to determine the leadership styles of teachers, especially in their relation to the students. Key words: Leadership, teacher leadership, leadership scale
