When is the least beneficial time to receive feedback on an assignment?

Receiving feedback after the paper has been graded and returned is the least beneficial time because, at this point, the opportunity for immediate improvement on that specific assignment has passed. The grading provides a summative assessment, reflecting how well the paper met the assignment criteria, but it does not allow for any changes or modifications to enhance the work further. Instead of guiding revisions or offering constructive criticism that could improve the understanding of the topic or writing skills for future assignments, feedback given after grading can only serve as a critique of what has already been submitted. This makes it less actionable compared to receiving feedback at earlier stages of the writing process, where adjustments can be directly applied to improve the quality of the work being produced.
