Note: You are currently viewing documentation for Moodle 1.9. Up-to-date documentation for the latest stable version is available here: Import groups.
As far as I understand, one can only import Group Placeholders (titles, descriptions, enrollment keys) with the .csv file. It is not possible to import group assignments = place students into those groups with the .csv import Correct? If it is so, then I think the helpfile is confusing :)
Currently it says: Required fieldnames - These fields must be included in the first record, and defined for each user.
"User" should be replaced with "group"
