Extension Letter

Extension letter


Punctuality is a quality that is very much sought after when it comes to students or employees. Submitting your work, assignments, etc. before or within the deadline helps in keeping things moving and is vital for teachers and managers, who themselves have deadlines to adhere to. However, sometimes things may not go according to plan, and you may be plagued with illness, an accident which may lead to you missing the deadline due to circumstances beyond your control.

In such cases, you will have to apply for an extension on your current deadline. An Extension letter could be written in the business world to request for more time to complete a task or contract, or it could be written by a student requesting for more time to finish off his project beyond the deadline. An extension letter should phrase the request courtesy with good reasons for the request to draw a favorable response.

The following is a sample of an Extension Letter.



Dr. David Chandler

Science Teacher

Gilligan High School





Peter I. Levi

Student Id.: TB39802

Science Project


Subject: Extension request to Science Project Deadline


Dear Dr. Chandler

I am writing this letter to request an extension on the submission date of my science report titled, “Beyond the Future” from the initial date DD/MM/YYYY, to DD/MM/YYYY.

I was taken ill after being caught in the rain on DD/MM/YYYY on my way back from the science center. It was a bad case of pneumonia which my general practitioner recommended full bed rest with some antibiotics. Given the heavy antibiotics that I had to take because of the infection, I wasn’t in any condition to work or study and hence, was unable to do any work on my project during these days. I am writing today for an extension of the deadline for my science project as I have not completed a fair portion of the document including the conclusion section as yet. I have taken the liberty to attach a copy of the doctor’s medical sheet and analysis of my ill health for any proof that you may require.

I shall attempt to submit earlier than the requested extension date if I can complete the whole report before then. I look forward to your favorable response. Once again, I would like to apologize for the inconvenience that this may have caused you.

Thank you for your kind understanding on my request.

Yours truly,

Peter Levi
