Hi kesposi2,

The Scores tab in your class shows the best score obtained across all attempts. If you want to view the first score, you'll need to use the Individual Student Activity Report.

While there's not a way to strictly enforce only one attempt at an assignment, you can check how many times the student completed the assignment by using the Manage tab. If you instruct your students to complete the assignment only once, you can then verify that they have followed these directions using that report.

I hope this helps! Please let me know if you have any additional questions!
