Post-evaluations give teachers a bit more control over assessments. If teachers want to use post-evaluations as graded assessments, they can give students access to the post-evaluations for a limited window of time.
If you click on the "Customize Lessons" tab (on the left-navigation menu) from your teacher dashboard, you can then select the class section from the drop-down menu, the lesson level from the radio buttons, and the specific lesson for which you want to enable the post-evaluation. You can enable the post-evaluation by toggling the switch to the "on" position. Students will then have access to the post-evaluations to complete until you de-activate the post-evaluation by toggling the switch to the "off" position.
