In addition to self-evaluation, you can also use the mutual evaluation feature to have users assess each other.
Unlike self-evaluation, peer evaluation involves entering an evaluation for each lowest-level task.
By setting an answer rank pattern for a task on this screen, you can use that task for mutual evaluation.
From the task selection box, select the answer rank pattern to be used for the mutual evaluation of that task, then click the "Update" button to complete setting the answer rank pattern for mutual evaluation.
If you do not want to use a task for mutual evaluation, select "Not set" and click the Update button, and the task will no longer be displayed on the mutual evaluation input screen, etc.
