Uploading submissions

Once you’ve created an assessment, the next step is uploading your students’ work. This article covers the standard upload flow.

Where to upload from

There are two main places you can upload submissions from:

  • The Start marking window — step 2 of the Start marking flow. Click Start marking from your home page or the Assessments page, then continue through to the Submissions step.
  • The assessment detail page — click Upload submissions at the top right of an assessment that’s already in the Ready state.

Dragging and dropping

In either place, you’ll see a drag-and-drop area. You have two ways to add files:

  • Drag files from your desktop or file explorer straight into the area
  • Click to open the file picker and select files from your computer

Files upload in the background as you add them. You can see progress for each file as it goes.

Supported file types

You can upload:

  • PDFs — recommended for the cleanest results, especially for typed or scanned work
  • Common image formats — JPG, PNG, HEIC, WebP

Word documents and other formats aren’t supported — if your students’ work is in Word, export it as a PDF first.

File size limits

Individual PDFs are capped at 50 MB. If a file is too big, you’ll see an error — try splitting the PDF or reducing image quality before re-uploading.

One file per student vs. combined PDFs

You have two upload modes for submissions:

The upload area lets you switch between modes at the top.

After uploading

Once your files are in, click Continue to move on (in the Start marking flow) or just close the dialog and your submissions will start processing. You can track progress on the Activity screen — see Tracking jobs: the Activity screen.

What if a file fails to upload?

Failed uploads show a red error indicator with a retry option. Common reasons:

  • File too large — split or compress the file
  • Unsupported format — convert it to a PDF
  • Network error — retry the upload

If you’re stuck, see My submission processing failed — what now? or get in touch at connect@marking.ai.

FAQs

Do I have to upload all submissions at once?

No. You can come back and add more submissions to an existing assessment at any time — see Adding more submissions to an existing assessment.

Can my students upload their own work?

Yes — you can share an upload link with your class. See Student upload links.

What happens after the file is uploaded?

Marking.ai prepares each file for marking and matches it to a student. Marking then runs in the background. Most submissions finish in a few minutes.

Can I delete a submission after uploading?

Yes — see Deleting submissions.
