Grading Student Work

1. Open your class section.
2. From the left menu, select the open-ended task you want to grade.
3. In the roster on the right, click a student's name.
4. Click the Grade button at the top of the page to enter Grading Mode.
   
5. In Grading Mode, you'll see two fields that AI can complete:
   
   • Score
   • Feedback
6. Click AI Grade in the bottom-right corner to grade the selected student's submission. 
   To grade every student's submission for the selected task, click AI Grade All next to the AI Grade button.

The AI will evaluate the student's work, assign a score, and generate personalized feedback based on the task requirements.

AI Grader will automatically process each student's submission. Depending on your class size, this may take a few minutes.
Using Grading Rubrics

AI Grader supports rubric-based grading.

If your question prompt includes a grading rubric, AI Grader will evaluate student work according to the rubric and assign points for each criterion.

For the most accurate scoring, make sure the total score of the task matches the total points in your rubric. For example, if your rubric totals 20 points, the task's maximum score should also be set to 20.

You can change the total score for any task in Course Edit Mode.

Tips for Best Results

• Use clear instructions in your question prompt.
• When possible, include a detailed grading rubric with specific scoring criteria.
• Ensure the task's maximum score matches the total points available in the rubric.
