On the other hand, the aspects of assessment are skills, understanding and person's knowledge. Evaluation could be for situations, people and conditions.
Third, the assessment could be established every day, month or could be at the end of the year. In fact, every time the teacher gives the students test she assesses them. In contrast, the evaluation must be every day.
