The workplace is now commonly used as a setting for acquiring vocational knowledge. This situated approach to learning offers access to authentic vocational activities and the guidance of more expert others. However, questions about the effectiveness of workplace learning processes need to be addressed. These questions are central to the evaluation and improvement of learning arrangements which aim to develop vocational skills. Draws on the findings of three recent studies of workplace learning conducted in Queensland, Australia, in order to address questions about the efficacy of workplace learning. Uses these studies to understand further potential and limitations of these learning arrangements.
