Does the student evaluation of teaching (SET) reflect the reality? In fact, there is a gap between SET scores and students' achievement. Therefore, the purpose of this study is to stress the measurement of classroom dynamics in light of the conceptualization of transformational leadership. In order to picture more accuracy of the teaching evaluation procedure, it is argued that teacher leadership behaviors could be a potential component for examining teaching evaluations. The research findings revealed the moderate positive relationships between instructor's transformational leadership and student engagement and satisfaction. Accordingly, it is conducive to include teacher leadership in the components of student evaluation of teaching. The implications and limitations of this study are discussed.
