If you're looking to run a survey for students after they have finished voting, you can do this with the 'Post Election Redirect URL' feature in the admin panel.
Step 1: Go to Admin > Setup > Evoting
Enter the URL that you want your students to go to when they have finished voting for all candidates. This could simply be to your homepage, or an external URL (e.g. Survey Monkey).
Step 2: Click Save!
Once you have saved, students will be automatically redirected to your chosen URL.
