This article describes an ongoing effort to train MSW students to practice motivational interviewing (MI) competently in the context of a university-community field education partnership model. Students in field placement are trained using the Motivational Interviewing Training and Assessment System and participate in a field seminar to hone MI proficiency. Mixed-methods preliminary evaluation data were collected to understand the impact of the training. Results suggest the Motivational Interviewing Training and Assessment System is promising for preparing social work students to use this evidence-supported practice competently. Implications from this practical example are discussed in relation to integrating an evidence-based practice such as MI into the social work curriculum.
