"First, it is important that teachers understand formative assessment as a process of inquiry and action that is embedded in their everyday practice - routine classroom assessment 'integrated with pedagogy to maximize its formative potential in promoting learning,' which involves the participation of students. For teachers who view assessment as something external, in competition with teaching and learning and that does not require student participation in the process developing this understanding will involve a considerable shift in their thinking and behavior."
