Hi Mr. A,

The list of students on the assignment scores page is sorted by display name, so if the student's name's are saved in "First Last" format they will be sorted by first name.

The only way to change this is to manually edit the students' display names to a "Last First" format via the students tab on the Teacher Dashboard. There are instructions for doing this here.

If you have a lot of students, you can ask them to change their own display names via their account settings page. Please note that they will only be able have access to this if they are at least 13 years old.

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