Increasingly the different ways in which learning can be conceptualised alongside debates within the field of human resource development (HRD) regarding its nature and purpose, potentially lead to confusion regarding how learning is to be assessed in the workplace. This article identifies some of the complexities associated with assessing learning in today's workplace and presents empirical findings suggesting that different aspects of an organisation's training and development system are likely to differentially determine the extent to which either formal or informal learning is assessed. Explanations as to why this may be the case are put forward.
