Enrolments generally come from Banner. Banner is the authoritative source of who is teaching/studying modules and the information on there feeds various systems.
Once a student is registered as studying the module in Banner, the enrolment will come through to Minerva by the following day.
University of Leeds staff need to be added to the SIAASGN form on Banner with an Assignment Type Code to give them the privileges they need on Minerva. This is normally done by the Student Education Service representative in your School, if you don't have one contact the Banner super user or Faculty Support contact who can arrange for Banner to be updated. You will need to fill in a Access to Modules form and give this to the person updating Banner in your School. Once added to Banner the enrolment will come through to Minerva by the following day.
If a student is not sitting a module officially and just needs to see Minerva content, any Instructor can manually enrol the student directly onto the module.
