Email to a Professor: Extension Request Templates (Polite + Direct)

Professional email templates for requesting assignment extensions from professors. Learn what to include, when to ask, and how to write effective extension requests.

What to Include in an Extension Request

A good extension request should include:

Essential elements:

  • Assignment name: Clearly identify which assignment
  • Original due date: Reference the current deadline
  • Requested new date: Specific date you're requesting
  • Brief explanation: Reason for the request (without oversharing)
  • Acknowledgment: Understand extension may not be granted
  • Contact information: Your name, student ID, course information

Helpful additions:

  • Progress update (if you've started the assignment)
  • Alternative proposal (if your first date doesn't work)
  • Apology for inconvenience
  • Promise to complete as soon as possible

When to Use Each Template

Polite Extension Request: Use for most situations - respectful and complete.

Due to Illness: Use when you're sick or have a medical issue.

Due to Emergency: Use for unexpected emergencies or crises.

With Progress Update: Use when you've made progress but need more time.

Brief Request: Use for simple, straightforward requests.

Alternative Proposal: Use when you want to propose a specific date.

Multiple Assignments: Use when requesting extensions on multiple assignments.

After Deadline: Use when requesting permission to submit late.

How to Use This Template

Copy the template above using the copy button, then paste it into your email client. Replace the placeholder text in brackets with your specific details — names, dates, company information, and any context relevant to your situation.

Customize the tone to match your relationship with the recipient. A message to a close colleague can be more casual, while outreach to someone you have not met should stay professional and concise. Remove any sections that do not apply to your situation.

We have included 8 variants above for different scenarios. Choose the one that best matches your situation, or combine elements from multiple variants to create the perfect message.

Before sending, proofread for typos, verify all names and dates are correct, and ensure any attachments mentioned in the email are actually attached. A small mistake in a professional email can undermine your message.
