 How can I add groups of users to my Moodle? First, let's look at two Moodle terms for groups of users. A cohort is a group of users created by the admin and available throughout the site or a category. You can enroll cohorts into courses. When users are removed or added to a cohort, they will disappear or appear in the courses where they're enrolled. A group, as Moodle uses the term, only exists within a single course. A course can have several groups and the teacher can create these manually or the admin can upload them with a file. This video looks at cohorts. If you need to create Moodle course groups in courses, watch our video on How can I add groups to my courses? Cohorts can be created manually or with a file upload. To create cohorts manually, your users need to already have accounts on your Moodle. From Site Administration, click Users and Cohorts. Click Add a new cohort. Give it a name. Choose whether you want this cohort available throughout the site or in a particular category. Give it an ID and description. By default, teachers in courses can see and add cohorts. If you don't want them to see this cohort, remove the tick check mark from visible. Click Save changes. On the next screen, click the Assign icon and move the users you want from the right into the left. To create and upload cohorts with a CSV file, your file needs to look like this. You upload it from Site Administration, Users, Cohorts, by clicking the Upload Cohorts tab. And here are the uploaded cohorts, not yet with any users. You can either add users manually from the Assign icon or you can upload them in a CSV file using the Cohort ID. See the documentation on cohorts for how to do this. Now your cohorts are ready to use. For teachers to be able to add cohorts for their courses, make sure you have the Enrollment plugin Cohort Sync enabled from the Manage Enrollment screen of Site Admin. To summarise, Moodle Groups uses in two ways. Site or category-wide cohorts and Course Groups. Cohorts can be created manually. Cohorts can be uploaded. Cohorts Sync must be enabled to add cohorts to courses.
