Workplace-based assessment: the need for continued evaluation and refinement.

Workplace-Based Assessment (WBA) has been an integral part of the UK Intercollegiate Surgical Curriculum Programme (ISCP) since 2007 (www.iscp.ac.uk). The UK Postgraduate Medical Education and Training Board (now part of the General Medical Council) has defined WBA as 'the assessment of working practices based on what trainees actually do in the workplace, and predominantly carried out in the workplace itself' (www.gmc.org.uk). This article reviews the purpose of WBA and the methods in current use. It also discusses the misuse of WBA and possible solutions, including redesign of the rating scales.
