Implementation Questions & Suggestions

• Should admin/instructors be able to apply late penalty for each individual question, or restrict it to the event as a whole?
• If a student has a valid reason for submitting a late evaluation, the admins and instructors should be able to revert or lessen the penalty applied to the student's mark.
• How should the late submission penalties be applied if a student submits a partially incomplete late evaluation?
• If an instructor or admin modifies the marks penalty scales after all the evaluations have been submitted, how would this affect the administered marks?
• How granular should the functionality be? Should an admin/instructor be able to apply different mark penalty scales to different students and groups?
