Research has indicated that numerous factors influence teaching performance, including nonacademic traits such as personality attributes, self-concept, commitment to teaching, and gender. This study compared the personality characteristics of elementary and secondary preservice teachers. Subjects were junior- and senior-level students (N=186) in an undergraduate teacher education program at a regional state university. All subjects completed a demographic survey that asked for basic information and included items designed to measure 16 dimensions of personality (warmth, mental capacity, emotional stability, assertiveness, impulsivity, conformity, boldness, sensitivity, trust/suspicion, imagination, social awareness, secure/insecure, traditional/liberal, self-sufficiency, self-discipline, and tension). The results indicated: (1) that both elementary and secondary education majors had high levels of conformity, social awareness, self-sufficiency, and self-discipline; and (2) that elementary and secondary education majors were significantly different on emotional stability, assertiveness, imagination, and self-sufficiency factors. Because the personality characteristics of teachers may be critical to the success of prospective teachers, an investigation such as this may provide valuable information for teacher recruitment and the advising of teacher education candidates.
