How to submit an assignment on Blackboard
Turn in work on Blackboard Learn without losing your submission — attach, confirm, and get a receipt.
Last updated June 1, 2026
Blackboard trips students up because the 'Submit' button and the 'Save Draft' button sit right next to each other. Here's how to actually turn it in, and how to confirm it landed.
- 1Open the assignment
Go into your course, find the assignment under Content or Assignments, and click its name to open the submission page.
- 2Attach your file
Under 'Attach Files,' click 'Browse My Computer' (or drag the file in). Blackboard accepts most formats — PDF and .docx are safest. You can add multiple files if needed.
- 3Add any text
If the assignment wants typed content, use the text box under 'Assignment Submission.' You can format it with the built-in editor.
- 4Click SUBMIT — not Save Draft
This is the step people miss. 'Save Draft' does NOT turn it in. Click the 'Submit' button to actually submit.
- 5Confirm the receipt
After submitting, Blackboard shows a green confirmation banner with a confirmation number. Screenshot it. That number is your proof if anything is disputed.
The #1 Blackboard mistake
Clicking 'Save Draft' and walking away. A saved draft is invisible to your professor and counts as not submitted. Always finish with the 'Submit' button and wait for the green confirmation banner.

Frequently asked questions
Why can't I submit my Blackboard assignment?+
Common causes: the due date passed and attempts are locked, your file exceeds the size limit, or you're clicking 'Save Draft' instead of 'Submit.' Check the assignment's availability dates too.
Where do I find my Blackboard confirmation number?+
It appears in the green banner right after you submit, and in your 'Submission' history. Screenshot it as proof.
Can I submit multiple files on Blackboard?+
Yes — use 'Attach Files' repeatedly before hitting Submit. All attached files go in as one submission.
