In this Gauge release, the Moderation page supports reopening submitted assessment attempts.
Reopen Student Assessment
Teachers and admins can reopen an assessment attempt for an individual student from the Moderation page. Students can only access reopened attempts that are in an open deployment window.
When a student resumes a reopened assessment, previously recorded responses will be retained and can be changed, unless the assessment displays one question at a time with backtracking disabled. The assessment timer will resume from its remaining time from the attempt.
