# Comparison of Assessments

In an exercise it is usual for a piece of work to be assessed twice. A student assesses their work before submitting it and the teacher then (re)assesses the work. The teacher's assessment uses the student's assessment as the starting point. An exercise allows the teacher to award a proportion of the grade to the student's assessment, the remainder of the grade is allocated to the teacher's assessment of the work. (The maximum grades for these are called "Grade for Student Assessments" and "Grade for Submissions" respectively.) Note that the grade from the student's assessment is not used. The student's assessment is given a grade based on how well it matches the teacher's assessment.

The degree of agreement between the student's and teacher's assessment is based on the differences between the scores in individual elements (actually the squared differences are used). The mean of these differences must be converted into a meaningful grade. The "Comparison of Assessments" option allows the teacher a degree of control on how these comparisons are converted into grades.
