I have had two requests from parents that have had the class average information for each assignment available to them at previous schools.  The parents say the information is important to them when evaluating their child's performance.  This information is made available to teachers in chart form when they click on a student's name in the grade book.  Parents see the same chart, with the exception of the class average for the individual assignments, when they click on one of the green grade books in their child's progress page.
