Extensions on Assignments

When extensions on assignments have been deemed necessary as a disability-related accommodation by AAS, it will be listed in the student’s accommodation plan.

This accommodation may be put in place for students with both episodic or persistent disability-related impacts.

Note: When a student has a disability that is episodic in nature, they may experience unpredictable flare-ups that interfere with their ability to complete the assignment by the deadline.

Students are required to request an extension from their instructor as soon as possible in advance of the deadline, but no less than one business day prior to the deadline, notwithstanding extenuating circumstances. Instructors benefit from reasonable time to consider and respond to requests.

Students and are encouraged to put their request in an email (template below), copying their Student Accommodation Facilitator if desired.

Students are not required to disclose the specific details about why they require an extension beyond saying it is one of their accommodations.

In exceptional circumstances when a student is unable to communicate directly with their instructor (e.g. they are hospitalized), they may request that their Student Accommodation Facilitator contact their instructor on their behalf to determine if an extension is possible.

Dear Professor [NAME]

My name is [YOUR NAME]. I am a student in your [COURSE NAME, CODE, & SECTION] class.

I am registered with AAS and sent you my accommodation plan, which includes extensions for assignments on a case-by-case basis.

Due to disability-related reasons, I am unable to submit [ASSIGNMENT] by [DUE DATE]. I am writing to request an extension with a proposed new deadline of [NEW DATE], with your permission. 

I have cc'd my Student Accommodation Facilitator, if you have any questions.

Thank you.




When requesting an extension, students are advised to be specific about how much extra time they need. The length of extension will vary depending on the nature of the assignment and course structure.

Instructors will determine an appropriate new deadline taking into consideration the student's request as well as:

  • Academic integrity - e.g. the proposed due date may not be reasonable if it comes after the rest of the class receive their work back with grades and feedback.
  • Impact on cumulative assignments or those that build on the assignment in question, putting the student in a position of falling behind.
  • Mitigating factors - e.g. the proposed due is very close to, or after, course grades are due creating the need for an INC (Incomplete Grade).

If a student asks for their Student Accommodation Facilitator's support when requesting an extension, AAS may not be able to intervene if the request is made less than one business day before the deadline. Retro-active requests are considered on a case-by-case basis when there are extenuating circumstance

There are situations when an instructor may not grant an extension:

      Extension requests for group work or group assignments.

      Extension requests close to, or after, course grades are due.

      Extension requests when an assignment has been graded and/or taken up in class.

Students or instructors that need support or consultation with an extension request can contact the Student Accommodation Facilitator (contact details available on the accommodation letter). 

Situations requiring further support may include:

  • Extension requests after the assignment due date.
  • A student has not met the agreed upon extended deadline.
  • There is disagreement between the student and instructor about this accommodation.
