What users can or can't do in a given Moodle course depends on their role in that course. Here are the roles that you may assign in your course.
Someone with this role can grade assignments. They can see (but cannot change) external grade columns created with the procedure described in Section 12.4, “Adding a gradebook column for an external grade”.
Someone this role can grade assignments, but they cannot even see external grade columns.
This role was created for use by the Advising Center at the Center for Student Success (CSS). If you assign this role to someone, they can see the entire gradebook but cannot change grades or change anything else in the course.
It is entirely up to you as course instructor whether you grant this access to the CSS.
The intent is that, especially for critical early courses such as Math 103 and 104, the Advising Center can use the gradebook to detect and intervene with underperforming students much earlier than midterms.
If you elect to grant this role, grant it only to the
Moodle account name elaine
(Elaine DeBrine-Howell).
Use this procedure to grant or revoke roles to other Moodle users.
This procedure works only for classes that are not
cross-listed. If your course is a meta-course
(cross-listed), you must enter one of the (normally
hidden) child sections and add the role there. If you
need to do this, send mail to <cms_master@nmt.edu>.
Procedure 9. Assigning or revoke a role
From the course page, under Administration on the left-hand side, click on .
In the Roles column of the table that appears, click on the name of the role you want to assign or revoke.
You will see two large blocks labeled existing users and potential users. Between them are and buttons.

To assign a role, click on the user's name in the right-hand window to highlight it, and click . The name will disappear from the right-hand window and appear in the left-hand window.
Role assignments take effect immediately. There is no “” step.
To revoke a role, click the name in the left-hand window to highlight it, then click .
Because the right-hand window has thousands of entries, you will probably want to use the search function instead. Enter a name, email, or part of a name in the field below the potential users block, then click . Only the names that match your seach pattern will appear; highlight and click as above to grant the highlighted name that role.
