It is a known fact that every profession needs to be developed during its practice. To be able to acquire this we need to know the characteristics of teachers related to their professional development. For this purpose this study tries to develop a scale to measure teacher characteristics which would help in designing in-service training programs to educate teachers. The first draft of the scale had 69 items and was administered to 99 senior teacher candidates in the faculty of education. The results were analysed by using exploratory factor analysis. As a result it was found that the scale contains three components, namely, teacher-student interaction characteristics with 13 items, characteristics related to teaching profession with 11 items, humanistic and justice characteristics of teachers with 9 items.
