Assessment can also help to further improve the teachers way of teaching. Formative assessment is one way to assess students. Formative assessments occur throughout the lesson or unit. Most of the time, formative assessments are not graded. Summative assessment usually occurs after the lesson or unit. The teacher uses this to see where the student's achievement is at this point. Summative assessment is also a way for students to show what they have learned. Summative assessments are usually used for reporting student achievement as well. It is very important to assess students so that you can help them in the best way possible.
