To add a certificate, switch editing on, go to your course’s homepage and click on the + Add an activity or resource button.
This will give you a screen full of options. Click on the Custom Certificate icon to open the New Custom Certificate page.
Enter the name for the certificate and (if you require one) a short description of it in the Name and Description fields. If you want this description to appear on your course homepage just below the link to the poll, you can tick the Display description on main page tickbox.
The Display mode for the options drop-down list sets whether the options are listed horizontally (i.e. on a line) or vertically (i.e. in a list).
There’s a variety of settings for creating a poll, each with a help icon that includes more information.
Click on the Save and display button and the certificate page will appear showing the name of the certificate and the number of recipients (there will be none so far).
