This study was designed to investigate relationships between student characteristics and changes during student teaching in anxieties, attitudes, and concerns about teaching. The subjects were three groups of students: 151 beginning student teaching, 162 completing student teaching, and a subset of 81 for whom both pre- and post-student teaching measurements were available. Less anxiety about teaching and less concern about survival was reported following student teaching. Attitude towards teaching remained positive for the total sample; however, males and secondary majors reported a less positive attitude and more anxiety about teaching following student teaching. Less anxiety and concern was reported about: (1) being observed while teaching; (2) feeling adequate as a teacher; (3) being accepted and respected by other professionals; (4) the ability to perform before a class; and (5) coping with parent-teacher conferences. The student characteristics of teaching field, gender, assurance of decision to teach, perceived effectiveness as a future teacher, anticipated grade level of teaching, and when the prospective teacher decided to become a teacher were found to be related to one or more of the measures.
