When students submit assignments, you review their work, assign a score, and provide feedback — all within the Lena Teacher App.
Before you begin: You need an assignment that students have submitted work for. See Creating Assignments.

​
Viewing submissions

1

Open the assignment

Navigate to your course → Assignments → tap the assignment you want to grade. You’ll see the assignment details and submission summary.
2

View the submissions list

You’ll see a list of all student submissions with:
  • Student name
  • Submission date and time
  • Whether the submission was on time or late
  • Grading status (graded or ungraded)
Assignment submissions list showing student names, submission dates, and grading status
3

Open a submission

Tap a student’s submission to view their work. You’ll see the student’s text response and/or uploaded files.

​
Reviewing student work

When you open a submission, you’ll see:
  • Text response — If the student submitted text, it’s displayed with formatting (markdown rendered for bold, lists, headings, etc.)
  • Uploaded file — If the student uploaded a file, you can view or download it
  • Submission timestamp — When the work was submitted
  • Late indicator — Whether the submission was after the due date

​
Grading a submission

1

Review the work

Read through the student’s response or downloaded file carefully.
2

Enter the score

Enter the student’s score out of the total marks (e.g., 18 out of 20).

3

Write feedback

Add written feedback for the student. This is your opportunity to:
  • Highlight what the student did well
  • Point out areas for improvement
  • Provide specific suggestions
Specific feedback is more helpful than generic comments. “Your analysis of the causes was thorough, but the conclusion could be stronger” is more useful than “Good work.”
4

Save the grade

Tap Save or Submit Grade. A confirmation appears, and the student will be notified that their assignment has been graded.

​
Handling late submissions

Submissions made after the due date are automatically flagged as late. You can see the late indicator in the submissions list. How you handle late submissions is up to you:
  • Grade normally — Give full marks if the work is good, regardless of timing
  • Reduce marks — Apply a late penalty (e.g., -10% per day late)
  • Leave ungraded — If your policy doesn’t accept late submissions
Lena doesn’t automatically apply late penalties. You decide how to handle late work based on your course policy.

​
Physical assignment grading

For physical assignments (work submitted in person), you enter grades directly without an online submission:
  1. Open the physical assignment
  2. Find the student in the list
  3. Enter their score and feedback
  4. Save
This records the grade in Lena’s grade system even though the physical work wasn’t submitted digitally.

​
Tips for efficient grading

  • Use the submissions list to track which students you’ve graded and which are still pending
  • Grade in batches — Set aside dedicated time to grade all submissions for one assignment
  • Be consistent — Use the same criteria for all students
  • Write actionable feedback — Tell students what to improve, not just what was wrong

​
Troubleshooting

  • Check that the student has actually submitted — look under the Submissions tab - If the assignment allows multiple submission types, check both text and file submissions - The student may not have submitted yet — check the deadline
  • Make sure the score doesn’t exceed the total marks for the assignment
  • Check your internet connection and try again - Try refreshing the page and re-entering the grade
