Despite their immense popularity and widespread implementation, research has yet to compare block and concurrent models of field. In filling this gap in the literature, this study evaluates the impact of each model on undergraduate social work students' professional development and emotional well-being. Sixty-eight students in BSW field placements at one large university participated in this study. Students were able to select which model of field to undertake, and, in general, most students selected block field placements because they wanted to graduate early. Conversely, students in concurrent field reported having more obligations outside of field, including family and other employment. Utilizing data collected from students and their field instructors, statistical analyses showed no differences in measures of professional competence, depression, assertiveness, or self-esteem between students in the two field models. In light of such findings, the authors discuss the implications of this study for social work programs and outline suggestions for future research.
