How to Write Leave Application: 7 Steps, Format and Templates

If you want to know how to write leave application letters that get approved quickly, follow one rule: say who you are, why you need leave, and exactly which dates, in the first three lines. Everything else, from the greeting to the closing, follows a fixed format that schools, colleges and offices in India all recognise.

This guide explains the seven steps, shows how the format changes for school, college and office, and gives you subject lines, email templates and a final checklist.

Key Takeaways

• Every leave application answers three questions early: who is asking, why, and for which dates.
• Students write to the principal or class teacher; employees write to their manager or HR.
• Use “Yours obediently” for school, “Yours sincerely” for office letters to a named manager.
• Email leave requests need a precise subject line, because managers scan their inbox by subject.
• Apply in advance for planned leave and on the day you return for sudden illness or emergencies.

How to Write Leave Application in 7 Steps

1. Choose the right receiver. Address the principal, class teacher, head of department, manager or HR, depending on who approves leave.
2. Add the date. Write the date you submit the application, in full, such as 12 October 2026.
3. Write a one-line subject. Name the type of leave and the dates, for example “Casual leave on 15 October 2026”.
4. Greet formally. Use “Respected Sir/Madam” in school or “Dear Mr. Rao” in an office.
5. State the request early. In the first paragraph, give your name, class or designation, the reason and the exact dates with the number of days.
6. Show responsibility. Students promise to cover missed work; employees mention handover and availability on phone.
7. Close and sign. Thank the reader, add the right sign-off, and write your name with class and roll number or designation and employee ID.

Types of Leave You May Need to Mention

Offices in India usually name the leave type in the subject line. Schools do not, but knowing the terms helps college students and new employees write the correct request.

Always check your school handbook or company leave policy, because the number of days and the rules differ between organisations. Similarly, government employees follow their own service rules, which name each leave type precisely.

How to Write Leave Application in Hindi

The structure stays the same in Hindi. Start with “सेवा में”, then write the receiver’s designation and address, the date and “विषय” for the subject. Use “महोदय” or “महोदया” as the greeting, and close with “आपका आज्ञाकारी शिष्य” in school or “भवदीय” in formal office letters. Keep the language simple and the dates clear, exactly as in English.

Checklist: How to Write Leave Application Without Errors

• Receiver, date and subject are at the top.
• The first paragraph has your name, the reason and the exact dates.
• The number of days matches the dates you wrote.
• You mentioned how you will cover work or hand it over.
• The sign-off matches the setting: “obediently” for school, “sincerely” for office.
• You signed the letter, and a parent signed if the school requires it.
• You attached a medical certificate for long illness.

Mistakes That Delay Approval

Even people who know how to write leave application letters make these slips when they are in a hurry.

• Burying the dates. Put them in the subject and the first paragraph.
• Over-explaining. One sentence of reason is enough.
• Casual greetings. “Hi” and “Hey” look careless in a formal request.
• Late submission. Planned leave should reach the approver in advance.
• Wrong channel. Many offices require leave on the HR portal as well as by email.
