Allocating detention manager permissions
Detention management is limited to users with the Detention manager permissions. School managers can allocate the permissions to all staff who need to be involved in the setup of detention sessions and the allocation of students to those sessions. Setting permissions for staff is covered in detail here.
It is advisable to limit the number of detention managers to those who administer whole school detentions. Teaching staff do not need detention manager permissions to create events which will lead to a managed detention.
