Note: Once a submission has been made to the assignment, templates can no longer be added or edited.
Template Requirements:
- Uploaded files must be less than 100 MBIf your file exceeds 100 MB, you can reduce its size by removing any images or save the file as a rich text or plain text file. You could also copy the text from the file and paste it into the Create Custom Template text box.
- Templates must have at least 1% words of text
- Accepted file types for upload: Microsoft Word, Excel, PowerPoint, WordPerfect, PostScript, PDF, HTML, RTF, OpenOffice (ODT), Hangul (HWP), and plain text.
Please note: All information is accurate at the time of posting but the Brightspace / Teams layout may have updated.
