We are currently unable to remove the section labeled as Graded Student Work from the Class Details page of Net Classroom. We are trying to only have students and parents view Report Cards in Net Classroom. Have removed the options for Grades, Assignments, Daily Grades, and Running Total from Configuration, Net Classroom. This makes sure the information does not show on the Class Details page, but the section is still there.
We are currently evaluating this issue and will update this article when we have more information.
