How to Submit a Blackboard Assignment (For Students)

When using e-submission tools be aware of any Known Issues via our E-Submission – Known Issues and Practical Considerations page

It is possible to submit an assignment electronically through Blackboard. You may find that your course instructor has set up a Blackboard assignment, which they expect you to complete. The instructions below explain how to submit an assignment through Blackboard.

Note that if you are uploading an assignment from home your internet connection may not be fast enough to upload a particularly large file (over 30MB) before the upload process times out. Therefore we recommend that if you wish to submit a file of over 30MB in size that you do so from a public workstation on campus or by using the SVE.

You are strongly recommended to convert your submission to a PDF file before submitting it. Office 365 (see below) has the ability to save files as PDFs.

Creating your Assignment

Did you know that all University of Southampton students have access to Office 365?

This provides you with

  • Office Online applications (Office 2016 based applications from your web browser)
  • Office for PC downloads (Office 2016 based applications)
  • Office for Mac downloads (Office 2016 for Mac based applications)
  • Office applications for iPad, iPhone and Android devices (Word, PowerPoint…)
  • Office Mobile for Windows phones

Using modern document creation programs substantially reduces the risk that you create incompatible files that your instructors are unable to open.

Locate the Assignment

Locate the Assignment

1. Locate the assignment within your Blackboard course. The screenshot above uses an example assignment.

2. To view further details or submit an assignment click on the name of the assignment.

If you have a group assignment to submit, the submission process is the same as for an individual submission, but only ONE member of your group needs to submit. Be sure to liaise with all members of your group so that you know who will be responsible for submitting the work.

Assignment Information

Assignment Information

3. The Upload Assignment page will appear. This is broken down into different sections.

You will see some information about the assignment, such as the due date and any instructions given by the tutor.

4. You will also see a write submission button. This would open a text box into which you could write your submission. Most of the time you would be uploading a file however, so move onto the next step.

Upload Assignment

5. Further down the page you can click on Browse My Computer to choose a document to upload. Locate the file you wish to upload and click on Open.

Please make sure that you do not have any spaces or special characters (e.g. !”£$%^&*()#’@[]{};:’|/,<>) in the filename.

Ensure that the file you wish to submit is not currently open for editing on your computer.

6. If you wish to add further files, click on Browse My Computer again and repeat the above step.

There is also an area to add any comments regarding your submission.

Submit or Save?

Submit or Save?

7. To Submit your assignment click on Submit. Be careful not to double click on the Submit button.

Make sure to click on Submit once only, and then wait until the transfer finishes. Do not double click on Submit, do not click the back button during the transfer, do not click on submit again even if you think it is taking too long. Failure to follow this guidance will lead to your assignment being corrupted.

Bear in mind that if you are submitting an assignment from home that the speed at which you can upload a file is much slower than on campus.

Important note about the Save as Draft button
The Save as draft option will save the assignment but WILL NOT submit the assignment to the course instructor – instead it allows a copy of the work to be saved in Blackboard, which may then be downloaded and worked on by the student at another time or location. If you wish to submit the assignment make sure to click on Submit.

If you do save as draft you can later upload an updated copy of the assignment.  It is vital that your new file has a different filename from the original file.  If you do not change the filename of your newer file the online preview will show the original draft to you, and if submitted, to your instructor.  Therefore you MUST change the filename on your computer for the newer file before submitting it in Blackboard.


At the top of the screen you will see a receipt. Copy and paste the receipt code, paste it into a document and save it somewhere safe. This receipt can be used to prove that you submitted your assignment.

8. On the right side your will see confirmation of the filename of your assignment, your comment, and a download link. On the left is the online preview. If the filetype of your file can be shown by the online preview it will let you know that the file is being converted and advise you of how long you should wait. The online preview will not display automatically, you should refresh your browser to view the online preview.

This shows the same submission once it has been made visible in the online preview.

Check that the online preview you see matches the content of your file. Pay particular attention to how any formulas, diacritics or special characters display. If you observe any difference take a screenshot of the online preview and your file side by side and contact ServiceLine.
Check that your assignment has uploaded correctly. Download the file and check that you can open it and that it matches your original file.

If you observe that your file has not uploaded correctly contact ServiceLine immediately.

Note: If multiple attempts are allowed a “start over” button will let you submit a replacement file. If you wish to resubmit but do not see this button you can make a request to your course instructor to clear your attempt so that you may submit afresh.



9. Note that if a Rubric will be used to mark your assignment you may view it by clicking on the icon shown above.

Example Rubric

Example Rubric

10. This is an example Rubric. With a Rubric your assessment is marked according to each criteria row and to what extent it fulfils each criteria. The maximum number of marks should be the total number of possible marks shown on the rubric. In the above case that would be five rows by the highest point per row, making ten possible marks.

The instructor has the option to adjust the marks after the rubric has been used.

You may or may not be shown what rubric criteria you attained when viewing your score. This is at the discretion of the instructor.
