In the United Kingdom, the number of mature students studying in higher education is diminishing. This is also the case within the subject of art and design. This article reports on a project "Mature Students Matter," a study that aims to widen participation in art and design education within a small specialist university. The approach was developed from a Research Development Fellowship, which provided a model for the project. A case study is used as a method of inquiry through which the project is described and evaluated using a form of narrative inquiry. The study found that the principles of Joint Practice Development (JPD) underpinning the design and development of the project enabled practitioners from different parts of the university to work together and to share similar aims, objectives and values in their research. Drawing some tentative conclusions, the project also found that the wider institutional context was important in the success of the project.
