Numerous sets of radio buttons or checkboxes lack a fieldset and legend on multiple pages in the Assignments tool.

Add/Edit Assignment page:

The Grading and Released Grade Notification Email Options radio buttons on the Add and Edit Assignment pages are not in a fieldset.

Options page:
The "please choose the display option for grading assignment page" on the options page are not in a fieldset.

Recommended Remediation
All radio button and checkbox groups should be in a fieldset.
