write apology letter

Here’s a model apology letter you can adapt:

Dear Ms. Carter,

I am writing to apologize for submitting my project after the deadline and for not telling you in advance. I understand that this caused extra work for you and was unfair to classmates who met the deadline. I take full responsibility: I managed my time poorly and should have asked for help earlier. I am sorry for the inconvenience and for breaking our agreed deadline.

To make things right, I have attached the completed project and would like to know whether I can complete an additional short reflection. I have also made a work schedule so that this does not happen again.

Thank you for your understanding.

Sincerely,
Alex Morgan

Why this letter works

1. Apologize immediately — say “I am writing to apologize for…”.
2. Name the specific problem — do not make the reader guess.
3. Acknowledge the impact — show that you understand how your action affected someone else.
4. Take responsibility — avoid excuses such as “but everyone else…” or “if you had told me…”.
5. Offer to repair the situation — suggest a realistic way to make things right.
6. Say what you will change — this shows that the apology is serious.
7. Close politely — use “Sincerely,” or “Yours sincerely,” for a formal letter.

Check: the letter states the mistake, accepts responsibility, recognizes the effect on the reader, offers a solution, and promises a change.
