This article reports on an interprofessional pilot project. This pilot study engaged 2nd-year, preservice, graduate early childhood education and social work students in an interprofessional training and collaborative activity as part of their graduate coursework. This study suggests that graduate early childhood education and social work students recognize the benefits of preservice interprofessional education, but the experience of working across disciplines can be very challenging. The challenges include a lack of clarity around professional roles and responsibilities, differences in understandings of children’s behavior, and a perception that there will be little opportunity for interdisciplinary collaboration in early childhood settings. Despite these challenges, participants expressed how important it was for them to experience firsthand some of the potential benefits and challenges to interdisciplinary collaboration as preservice students.
