There are two levels of access control available in the online COE.
1. Classroom level access - this is set by teachers for each group. By default, access is closed and teachers must open access when they are ready to have students work. It is possible to either open access for a specified length of time or set a recurring access schedule.
2. On-demand access - since students should not have access to their on-demand items before the on-demand session, the titles for these tasks or prompts are hidden from the student until the teacher opens access. This is a separate process from opening the group access.
