Abstract
Recent developments in British higher education have included taking a close look at work‐based learning, in particular its assessment (and its integration within academic programmes of study). However, two questions which are still continuously being asked are (a) to what extent are assessments of work‐based learning valid and reliable, and (b) can they count towards the award of university degrees and diplomas? These questions are becoming increasingly important as there seems to be a growing trend for students to assess their own learning at the workplace (through reflection and analysis and the use of diaries and self‐development journals). This article addresses the above issues by drawing on classical test theory (for an understanding of the fundamentals of validity and reliability) and by examining how the different notions of validity and realiability may be applied in the context of assessments (and self‐assessments) in the workplace. The article concludes that, under certain stated conditions, it is indeed possible to determine whether assessments (and self‐assessments) of work‐based learning are valid, reliable — and comparable.
