How to Write an Application for Leave in School: Format and Examples
A leave application is usually the first formal letter a student ever writes. It is short, it follows a fixed shape, and it has a real consequence: attendance records, internal assessment marks and exam eligibility all depend on absences being accounted for properly.
Most applications that get sent back are not badly written. They are missing a date, a class section or a clear number of days. This guide covers the standard format, what changes when a parent writes it instead of the student, four samples you can adapt, and the errors that slow down approval.
When You Need to Write One
Schools expect a written application whenever a student will be absent for a full day or longer, and in most cases for a planned half day as well. Common situations include illness, medical appointments, family functions such as a wedding, travel out of station, a bereavement in the family, participation in an external competition, and religious observances.
A phone call to the office is not a substitute. The written record is what the class teacher files and what the attendance register is reconciled against at the end of the term. Where the absence is unplanned, the application is submitted on the day the student returns.
The Standard Format
The format follows the conventions of a formal letter, trimmed down. Keep the whole thing to one page, and in most cases to under 150 words of body text.
The Parts of the Letter
- Receiver’s address: To, The Class Teacher or The Principal, followed by the school name and city
- Date: written in full, for example 12 October 2026
- Subject line: one line stating the purpose, such as Application for three days of sick leave
- Salutation: Respected Sir or Respected Madam
- Body: the reason, the exact dates of absence, and the number of days
- Closing request: a polite line asking for the leave to be granted
- Sign-off: Yours obediently or Yours sincerely, followed by name, class, section and roll number
The subject line does more work than students expect. A teacher handling forty applications a term reads the subject, checks the dates, and files it. If the dates are buried in the third sentence, the letter takes longer to process.
Student Application Compared With Parent Application
Both are accepted, but they differ in who is addressed, how the request is phrased and what identification is needed. best icse schools in Bangalore generally ask for a parent-signed application for any absence longer than two days, and for all medical leave.
Tone and Language Rules
The register is formal but plain. A few rules cover almost every case.
- State the reason in one sentence. Do not describe symptoms in detail or explain family circumstances at length.
- Give exact dates rather than vague spans. Write from 12 October to 14 October, not for a few days.
- Do not use contractions such as can’t or won’t.
- Avoid apologising repeatedly. One polite request is enough.
- Mention a plan to cover missed work if the leave is longer than two days.
Schools also look for consistency. If a medical certificate is promised in the letter, it has to arrive. Teachers in the top icse schools in Bangalore typically ask for the certificate at the point of return, not later in the term.
Sample Leave Applications
Sample 1: Sick Leave, Written by a Parent
To, The Class Teacher, New Horizon Public School, Indiranagar, Bengaluru
Date: 12 October 2026
Subject: Application for three days of sick leave for my daughter
Respected Madam,
My daughter Ananya Rao, a student of Class 5 B, roll number 18, is unwell with viral fever and has been advised rest by our doctor. She will not be able to attend school from 12 October to 14 October 2026, a period of three days.
I request you to kindly grant her leave for these dates. I will submit the medical certificate on the day she returns, and she will complete the missed classwork at home.
Thank you.
Yours sincerely, Meera Rao, Mother of Ananya Rao, Class 5 B
Sample 2: Family Function, Written by a Student
To, The Class Teacher, New Horizon Public School, Indiranagar, Bengaluru
Date: 3 November 2026
Subject: Application for two days of leave to attend a family wedding
Respected Sir,
I am Karthik Nair of Class 8 A, roll number 22. My elder sister’s wedding is being held in Mysuru on 6 November 2026, and my family will be travelling on the previous day. I will therefore be absent on 5 and 6 November 2026.
I request you to kindly grant me leave for these two days. I have noted the portions being covered and will complete all assignments before I return.
Thank you.
Yours obediently, Karthik Nair, Class 8 A, Roll Number 22
Sample 3: Half Day Leave
To, The Class Teacher, New Horizon Public School, Indiranagar, Bengaluru
Date: 21 January 2027
Subject: Application for half day leave on 21 January 2027
Respected Madam,
I am Diya Sharma of Class 7 C, roll number 9. I have a dental appointment at 1.30 pm today and need to leave school after the lunch break.
I request you to kindly permit me to leave at 12.45 pm. My mother will collect me from the school gate.
Thank you.
Yours obediently, Diya Sharma, Class 7 C, Roll Number 9
Sample 4: Leave Application by Email
Many schools now accept email for short notice absences. The structure stays the same, with the subject line moved into the email subject field.
Subject: Leave application for Rohan Iyer, Class 3 A, 9 and 10 February 2027
Respected Madam,
My son Rohan Iyer of Class 3 A, roll number 14, will be out of station for a family commitment on 9 and 10 February 2027. I request you to kindly grant him leave for these two days. He will catch up on the work covered in class on his return.
Thank you.
Yours sincerely, Sanjay Iyer, Father of Rohan Iyer, Contact: 98XXXXXX21
Mistakes That Delay Approval
- Leaving out the class and section, which makes the letter hard to file
- Writing tomorrow or next week instead of calendar dates
- Submitting the application after the absence without explaining the delay
- Using casual language or messaging shorthand in an email
- Promising a medical certificate and not attaching it
- Asking for open-ended leave with no return date
How Schools Process These
The class teacher records the leave against the attendance register and passes longer requests to the coordinator or principal. For absences beyond three consecutive days, most schools require a medical certificate or a written reason from the parent before the leave is marked as approved rather than absent.
That distinction matters at the end of the year, when attendance percentage is calculated for board eligibility. Even at nursery schools in Bangalore, where marks are not at stake, a clean record helps the school track illness patterns and plan classroom hygiene.
Key Takeaways
- Every application needs a date, a subject line, exact dates of absence and the student’s class and section.
- Students sign off with Yours obediently; parents use Yours sincerely.
- Keep the reason to one sentence and skip unnecessary detail.
- Leave beyond three days usually needs a medical certificate or a parent-signed letter.
- Submit on the day of return if the absence was unplanned.
Conclusion
A leave application takes five minutes to write once the shape is familiar. Put the dates in the subject line, state the reason in one sentence, identify the student properly, and sign off correctly. Students who learn this format in middle school carry it into college applications, internship requests and workplace emails, where the conventions barely change.
Frequently Asked Questions
How long should a school leave application be?
Under 150 words of body text. Three short paragraphs are enough: the reason, the dates, and the request.
Should a student or a parent write the application?
For a half day or a single planned day, a student can write it. For illness, travel or any absence longer than two days, most schools ask for a parent-signed letter.
Is Yours obediently or Yours sincerely correct?
Students writing to a teacher or principal use Yours obediently. Parents writing to the school use Yours sincerely.
Can a leave application be sent by email?
Most schools accept email for short absences. Use the same structure, put the student’s name, class and dates in the email subject line, and include a contact number.
What if the leave was unplanned?
Submit the application on the day the student returns, and add one line noting that the absence was unexpected.
Is a medical certificate always required?
Not for one or two days. Most schools ask for one when sick leave runs beyond three consecutive days, or when the absence overlaps with an examination.
Can leave be refused?
Yes. Requests during examination periods or where attendance is already below the required threshold may be declined, which is why long leave should be applied for well in advance.
