Hi @ClaudiaJackson ...
This depends on whether or not the Assignment Enhancements for Students feature option has been turned on at your school within Canvas. If it has not been turned it, students always see their most recent submission for the assignment but not previous submissions of the same assignment. (However, instructors are always able to see all submissions from a given student.) If the Assignment Enhancements for Students feature option has been enabled by your Canvas administrator, then students can use a drop-down menu to view past submissions. Here are a couple student Guides for you to look at:
I hope these Guides will be helpful to you. Sing out if you have any questions...thanks!
