Evaluation is an essential part of the educational process. The focus of evaluation is on local quality improvement and is analogous to clinical audit. Medical schools require evaluation as part of their quality assurance procedures, but the value of evaluation is much greater than the provision of simple audit information. It provides evidence of how well students' learning objectives are being achieved and whether teaching standards are being maintained. Importantly, it also enables the curriculum to evolve. A medical curriculum should constantly develop in response to the needs of students, institutions, and society. Evaluation can check that the curriculum is evolving in the desired way. It should be viewed positively as contributing to the academic development of an institution and its members.
