There are, however, some disadvantages with summative assessments should be noted. A poor result on a summative assessment can be a strong de-motivator for struggling students. It is also an assessment which does not give the teacher much opportunity to make up for deficiencies, as it is the final assessment before moving on to a new unit, lesson, etc.. Also, depending on what form a summative assessment takes, it may inaccurately represent certain students who do not excel in certain types of tests.
