In past decades, teachers would design a unit of study that would typically include objectives, teaching strategies, and resources. The student's mark on this test or exam was taken as the indicator of his or her understanding of the topic. In 1998, Black & Wiliam produced a review that highlighted that students who learn in a formative way achieve significantly better than matched control groups receiving normal teaching. Their work developed into several important research projects on Assessment for Learning by the King's College team including Kings-Medway-Oxfordshire Formative Assessment Project (KMOFAP), Assessment is For learning (Scotland), Jersey-Actioning-Formative assessment (Channel Islands), and smaller projects in England, Wales, Peru, and the USA.
