When a student schedule changes from one section to another, Campus does not have a method to copy their grades from the old to the new section even though it is the same course and teacher. One of the pre-requisites would be for the teacher to have identical classes in both sections to enable a copy feature which unless the teacher is meticulous, does not happen.
Procedure to get grades for the new section -
If student is not showing on old roster >> Go down to Account Settings >> Uncheck the box "Show Active Students Only" >> Go to gradebook and look at grades, print progress report as needed, etc. >> Go to the new class/gradebook for student - enter grades,
