Overview: This will show teachers how to prevent students from logging in and resuming any assessment (comprehensive and formative) while it is in progress.
Step One: Go to the Class tab to view the class you wish to disable.
Step Two: Go to the "Disable Tests" column.
1. Check the top box to disable logins for all students in class.
2. Check any box within any individual student's row to disable all assessments for that student.
Step Three: To resume assessments, simply uncheck the boxes that are checked.

Note: This feature works by disabling the assessment icons when a student logs into his or her account. It will clearly say that the assessment has been disabled by the teacher.
