OIT Home > OIT Knowledge Base Search Knowledge Base: Can I set the duration of availability for my Blackboard Learn course site? Yes, this is an option within Customization, but please do not set the Course Duration of your course site. While you technically can set the duration of availability for your Blackboard Learn course site, there is no need to, as courses are made available and unavailable to students automatically every semester. Again, please do not attempt to set Course Duration. If there is a situation in which you believe setting Course Duration is necessary for your course site, please contact the OIT HelpDesk at (865) 974-9900 or use the OIT HelpDesk Contact Form.Need more help?
