In this paper we propose a model for an International Common Project that is designed to have students from more than one country working on the same project at the same time. We define a project as a substantial piece of (individual) work undertaken by a student under the guidance of a supervisor. The benefits to the student arising from such an international project are significant but the difficulties cannot be ignored. A model is described which is designed to maximise the international element whilst minimising the consequences of the difficulties. The model requires the participating institutions to work closely to define suitable projects and identify students to work on them. Initially students work alone or with only minimal contact. As each project evolves the students will increasingly co-operate to manage tasks associated with the project amongst themselves. At all times the student's individual contribution will be measured for assessment purposes. This paper describes the background to the project and the ways the difficulties which have been identified might be minimised. The problems in managing such a project are discussed and a method proposed to unify the approach taken to the project management and assessment process by the participating institutions. The model proposed will be piloted this fall with involvement by universities from France, Germany, the UK and the US. Various management tools will be developed to assist with the running of this pilot. Further testing and refining of the model will be carried out in the spring when a second set of projects will be run.
