Understanding Late Penalties
How late penalties work and strategies for managing deadlines
Why Instructors Use Late Penalties
Late penalties serve several purposes in academic settings:
- Fairness: Students who submit on time shouldn't be disadvantaged compared to those who take extra time.
- Time management: Deadlines help develop professional skills needed in careers.
- Grading logistics: Staggered submissions make it harder for instructors to provide timely feedback.
- Learning progression: Assignments often build on each other, and delays can disrupt learning.
Common Late Penalty Types
Percent of Max Per Day
Deducts a fixed percentage of the maximum possible points for each day late. Example: -10% per day on a 100-point assignment = -10 points per day.
Percent of Earned Per Day
Deducts a percentage of what you actually earned, not the max. This is proportionally fairer but less common.
Flat Points Per Day
Simple flat deduction per day late. Example: -5 points per day regardless of assignment size.
Fixed Penalty If Late
A one-time penalty applied if late at all. Example: -20% if submitted after deadline, whether 1 hour or 1 week late.
Strategic Insights
- Calculate the break-even: Sometimes it's worth taking a small penalty to improve your work substantially.
- Prioritize high-weight assignments: A 10% penalty on a 20% assignment hurts more than on a 5% assignment.
- Submit something: Partial credit with a late penalty usually beats zero for not submitting.
- Know your policy: Some instructors accept late work up to a cap; others don't accept it at all.
Important Considerations
- • Grace periods may exist - check your syllabus
- • Extensions are often available for legitimate reasons
- • Some assignments may not accept late submissions at all
- • LMS timestamps are usually the official record
- • When in doubt, communicate with your instructor
