Homework grading Each problem will be graded by a designated student grader in the class and by the TA. When you are the designated grader, you have the following responsibilities:

  1. On the due date, collect the homework papers for the problem.
  2. Look over the solutions and based on this, write (a) a model solution to the problem, and (b) a grading summary. The summary categorizes the kinds of mistakes or inadequate solutions you've noted and how much score you think should be deducted for each sin.
  3. Meet with the TA and together go over model solution and grading summary, making adjustments as needed. This meeting must be within one week of the due date of the problem. If doubts remain, also consult Lecturer.
  4. Grade the papers according to the plan. The max score is 10 points. Write explanatory comments on the papers for each reason that points are deducted.
  5. Review the grading with the TA (and possibly Lecturer). Submit the graded papers to the TA (for recording of grades and return to the class). This must be done within two weeks of the due date of the problem.
  6. The designated grader does not submit an individual solution, but gets a grade on the problem from the TA based on the grading process.
