This article reports on a six year longitudinal study designed to investigate whether providing exemplars to students during their course of study has an impact on their results. Over the course of six years in the same law unit of study undertaken at an Australia university, selected groups of students were provided with exemplars whilst others groups were not provided with exemplars. Changes to the results achieved in the final exam were observed and reported between these different groups. The findings of this study indicate very clearly that exemplars have a significant positive impact on the results achieved by students.
