Assessment is an integral part of the learning process; its existence cannot be ignored because it becomes a part of the unity of learning. Assessment is an absolute necessity in mathematics learning, and the choice of assessment type needs to be consideredIn education development, the role of research results that explore assessment, including in mathematics learning, is a form of proving how assessment is used in the classroom. To see the extent to which the position of assessment develops, as well as how the implications of assessment in mathematics learning, as well as the extent to which assessment theory plays a role in the formation of teacher understanding of its implementation in learning, it is necessary to conduct a study of developing research. For this reason, a descriptive literature review analysis was carried out so that a study can be described based on the reflection of the use of assessment in mathematics learning. In detail, reflection on the use of assessment will be discussed further in this paper.
