For example, if well managed, group projects promote various interpersonal skills that are relevant to the workplace. However, they are not necessarily a good way of developing a wide knowledge base in a large number of students in a short period of time. Generally, the promotion of ‘transferable’ skills is time-consuming and may draw resources away from more traditional teaching objectives.
 In evaluating assessment, focus is placed on its ‘validity’ – the relationship between assessment and the desired learning outcomes. Assessment should also be evaluated on its reliability (consistency of marks, etc.) and practicality (time, cost and legitimacy).
