An assessment is important because it helps us to determine that students understand and are absorbing the knowledge given to them. With the help of an assessment, one can figure out if the goals of education are being met or not. In the modern world, students must not only understand the basic concepts of reading, writing or arithmetic calculations, they must also be familiar with the challenges that this new world imposes upon them. They are required to master the skills of critical thinking and quick observation in order to make inferences. Exams, essays, projects, etc are all different methods to assess students.
