A research project was conducted studying the optimal duration of a service-learning project for junior level communication disorders students at Truman State University. The service-learning project involved inter-professional collaboration between Truman State's Communication Disorders Department and staff members at Kirksville's Early Head Start Center. The junior level communication disorders students provided early language enrichment services for the students at Kirksville's Early Head Start Center for varying lengths of time. Four groups were studied, including three experimental groups and one control group. One experimental group attended Early Head Start for a ten week period, one group attended for five weeks, the third experimental group attended for two weeks and the control group did not attend Early Head Start at all. Surveys were used to assess the differences that occurred in the knowledge and comfort level among the various experimental groups and the control group in order to conclude which duration of time was most optimal for the service learning-experience.
