Teachers can use formative assessment to monitor students' learning by providing regular and timely feedback on what they've done well and what they need to improve on. It can take a variety of forms, from informal quizzes to verbal feedback on a piece of work. To be effective, formative assessment needs to take place on a daily basis during teaching and learning.
Formative assessment is used to help teachers decide how to further develop student understanding, identify gaps in the pupils' learning, and target those gaps by adjusting their planning sequences of learning to address those gaps.
