The purpose of this study is to examine student teachers' anxiety related to classroom management in terms of behavior and teaching management. The study is carried out with the participation of 700 student teachers attending Ziya Gökalp Education Faculty at Dicle University in the 2007–2008 academic year. In order to determine their anxiety levels concerning behavior management and teaching management, the scales of “behavior management anxiety” and “teaching management anxiety” are used. Data are analyzed with correlation (Pearson), t test, and analysis of variance techniques. The Scheffé test is used to test significance. According to the student teachers' participation to school experience and to their branches, significant differences are determined between all subscales of behavior management anxiety levels.
