For every assignment, test, and content item in Blackboard, you have the ability to control when it becomes visible and for how long.
When adding or editing the material or tool, look for the “Display After” and “Display Until” options shown in this image.
NOTE: Make sure that you check off BOTH Display After and Display Until. You can enter an “until” date that extends after the semester is over, but if you don’t check it and indicate an end date, there might be problems with the link not displaying.
