Assessment is a complex process. Research findings and implications often reveal discrepancy in assessment outcomes and show the narrowing impact of curriculum and teaching methods. This paper intends to analyse the practical possibilities for interdisciplinary research and professional development while considering the opportunities for improving assessment strategies and integrating new testing modes designed to raise achievement standards by developing students’ understanding of their learning goals, the criteria by which they are assessed and their ability to evaluate their own work. Particular focus is given to language assessment.
