Sick Leave Email to Professor: Templates & Academic Etiquette

Communicating an illness to a university instructor requires more formality than a text to a colleague. Professors manage hundreds of students; therefore, your email must be concise, professional, and contain all necessary course identifiers.

The Anatomy of an Academic Sick Leave Email

To ensure your absence is excused, your email should include:

  1. Clear Subject Line: Include your course code and section.
  2. Formal Salutation: Use "Dear Professor [LastName]".
  3. The Impact: State exactly what you are missing (lecture, quiz, or seminar).

Template: Missing a Standard Lecture

Subject: Absence: [Course Code] - [Your Name] - [Date]

Dear Professor [Last Name],

I am writing to inform you that I am unable to attend today's class for [Course Name] due to a sudden illness.

I plan to review the lecture slides and complete the assigned readings from the syllabus once I am feeling better. If there were any in-class announcements I should be aware of, I will consult with my classmates.

Thank you for your time and understanding.

Sincerely, [Your Name] [Student ID Number]


Pro Tip: Extension Requests

If your illness interferes with a submission, don't just say you're sick. Ask for a specific extension (e.g., "I am requesting a 48-hour extension") and attach your medical documentation if you have it ready.
