Translate the Difference Between Formative and Summative Assessment

A school report or course handbook used the words formative and summative and assumed you knew what they meant. You did not. This explains both with concrete examples and shows why the difference matters for how you or your child should approach the work. You come away able to read the report without quietly nodding along.
