An internship experience is an important part of undergraduate education that is necessary for graduating students to be competitive in tight labor markets. Only recently has empirical research addressed the elements of effective internships. This study identified elements of 173 site supervisors’ overall ratings of intern performance. Interns’ ability to communicate, take action independently, learn quickly, and complete tasks in a timely manner significantly influenced the supervisors’ overall assessment of intern performance. Other factors such as problem solving and decision making did not significantly add to our understanding of supervisors’ overall assessments. Future research is suggested and implications for preparing students for internships are discussed.
