Moodle course formats can be changed at any time, not just when choosing an initial format. The only consideration in changing formats is that courses using the Tiles format that have custom tile backgrounds will lose this property if changed to a different format (and will not restore them if the format is reset to Tiles). If you need to change a course format from Tiles with custom tile backgrounds for printing, or some other reason, contact iTech and we can create a copy of the course, allowing you to keep the original course intact.
Changing the format

- From the main course page, select the settings wheel and choose Edit settings.
- On the settings page, scroll down to Course format and expand that section by clicking on the title or the arrow next to it.
- From the drop-down list, select the new format you wish to use. There will be a brief pause while Moodle loads the options for the new format.

- Set any desired custom settings for the format and click on Save and display at the bottom of the page.
