Deadlines, accommodations, and extensions policy


Accessibility Services

My general policy is to grant requests from Accessibility Services (AS). If I do not think an AS request is feasible, I will seek extra support from UofT to help make it happen. Please show this webpage to AS staff before they send me a letter, to give them an idea in advance of what accommodations are feasible in my courses. Please submit AS accommodation requests at least one week before the pertinent due dates of graded work, to allow time for logistical planning (I am also disabled).

Illness or injury

Standard UofT policy is that students needing accommodations for illness or injury should see a Dentist, Nurse/Nurse Practitioner, Physician/Surgeon, Psychologist, Psychotherapist or Social Worker registered and licensed in the Province of Ontario in person, and have them fill out a Verification of Student Illness or Injury (VSII) form.

Independently, I recommend taking personal health notes for your own records, like in a lab book. Careful documentation of how things are going makes discerning patterns easier over time. In turn, this affords more confidence in requesting help from a college registrar or academic accommodations from a course instructor.

Note that the VSII form concentrates on only the timeline and severity of the illness/injury. The reason for this is that those are the only two factors that matter for the creation of altered grade weighting (for missed homeworks) and/or appropriate make-up work (for missed exams) to cover the exceptional circumstances. Private medical details are none of the instructor's business, and you should not have to disclose them in order to get accommodated fairly.


Deadlines help to provide temporal scaffolding for your learning. This is the primary academic reason why you should aim to respect deadlines for turning in graded work. Procrastination tends to snowball, making delays cascade and go nonlinear. For my part, I make a genuine effort not to be a deadline terrorist (see Extensions), and I encourage taking advantage of my regular weekly office hours to get tips on homework problems and studying for exams.

The Instructors' Handbook makes clear that instructors must turn back a certain percentage of the final grade to the whole class by the drop deadline. I adhere to that rule strictly, with time to spare, because it provides important academic transparency for students. The only exception may occur when a student has obtained an incompatible extension on term work.


In the spirit of further transparency, here are my rules on extensions.

  1. Homeworks/essays/reports are due on the dates specified, at the beginning of class. The lateness penalty per day is 5%, up to a maximum of seven days. Assignments handed in more than one week after deadline will normally not be graded.
  2. Each student gets a bank of seven Grace Days per semester, which allows handing in assignments late without penalty. You may use all seven on one assignment, or spread them out differently. My only rule is that you must inform me that you will be using a specific number of Grace Days at least 24 hours before the original due date.
  3. The maximum extension for any given homework/essay/report is normally one week. Assignments turned in late will be returned late.
  4. Homeworks/essays/reports submitted more than one week late cannot normally be counted. Re-weighting remaining term work to cover the missing grade is the primary remedy available; the other is to re-weight onto the final exam.
  5. Extensions beyond Grace Days or AS requests may be granted in exceptional circumstances, at my discretion. Present me with a good case for leniency and I am likely to grant it.

I hope this information helped. Let me know what else I can do to support you in reaching your academic goals.
