Every school student will one day face a simple but important situation: they know in advance that they will be absent from class. It may be a family wedding fixed for next week, a cousin's marriage ceremony in a distant district, an urgent journey with parents, or a religious programme that falls on school days. In such cases, a leave application written *after* the absence is no longer enough — the polite, responsible, and officially accepted practice is to apply for leave *before* the absence begins. That is exactly what a leave in advance application is, and examiners in Class 6, 7, 8, SSC and HSC regularly set this item because it tests whether a student understands formal communication, not just memorised paragraphs. This post explains what a leave in advance application means, gives you the exact formal format used in examinations, provides three ready-to-use samples for different situations (to the Headmaster, to the Principal, and one written by a parent), lists reusable phrases and sentence patterns, shares exam-scoring writing tips, and answers the most common questions students ask about this topic.

What Is a Leave in Advance Application?

A leave in advance application is a formal written request submitted to the Headmaster or Principal *before* the days of absence, seeking permission to remain absent from school for a specific period. The phrase "in advance" is the whole point: instead of explaining an absence that has already happened (as in a regular sick-leave application), the student informs the authority beforehand, states the reason, mentions the exact dates, and respectfully asks for permission.

The difference between a leave in advance application and a regular leave application is mainly one of timing and tone:

• Regular leave application (post-facto): written after the absence, usually beginning with phrases like "I could not attend school yesterday because I was suffering from fever." The applicant is *informing* the authority of something already done.

• Leave in advance application: written before the absence, using phrases like "I beg most respectfully to state that I shall remain absent from school from 12 November to 14 November as I have to attend my elder sister's wedding ceremony." The applicant is *seeking permission* for something not yet done. That is why advance applications usually close with "I shall be highly obliged if you grant me leave of absence" or "Kindly grant me leave of absence" — the leave is requested, not merely reported.

This item is most useful, and most often asked, in the following situations:

• Family functions: weddings, marriage ceremonies, naming ceremonies, or other family events scheduled in advance.

• Urgent journeys: a sudden but pre-known trip, such as going to the village home, visiting relatives, or accompanying parents somewhere.

• Religious and social programmes: events known days or weeks earlier, where the student knows the exact dates of absence.

Typical examination phrasings for this item include:

• "Write an application to your Headmaster for leave of absence in advance for attending your sister's wedding."

• "Write an application to the Principal of your college for leave in advance for an urgent journey to your village home."

• "Suppose you are a student of Class 8. You want leave in advance for a family function. Write an application to your Headmaster seeking leave of absence."

Whenever the question mentions "in advance," "beforehand," or names an event that is *coming* (will be held, is to be held), the examiner wants the advance-notice style — permission-seeking tone, future dates, and a closing that requests rather than reports.

Leave in Advance Application Format

A formal leave in advance application follows the same 7-part format used for all official applications in school examinations. Memorise this format once and you can use it for any application item:

1. Sender's address — the applicant's address (or school name and class, roll number) at the top left or top right.

2. Date — written clearly below the address, e.g. "10 November 2026."

3. The recipient — "To / The Headmaster / The Principal" with the school name and address below.

4. Subject line — a one-line summary such as "Subject: Prayer for leave of absence in advance."

5. Salutation — "Dear Sir," or "Respected Sir," (use "Madam" if the head of the institution is female).

6. Body — three short paragraphs: (a) introduction of the applicant (name, class, roll), (b) the reason with exact dates of absence and the request for permission, (c) a polite closing line of gratitude.

7. Closing — "Yours faithfully," or "Yours obediently," followed by the signature, name, class and roll number.

Note two format points that are special to leave in advance applications. First, always write the dates as *future* dates and mention both the first and the last day of absence (for example, "from 14 November to 16 November"). Second, always include one sentence that assures the authority you will make up the lessons, such as "I shall try my best to make up the lessons missed during my absence" — examiners reward this responsible touch.

Sample 1: Leave in Advance Application to the Headmaster for a Family Function

The following sample is suitable for Class 6, 7, 8 and junior classes. The reason is a family wedding — the most common examination situation for this item.

House No. 14, Road No. 7

Mirpur, Dhaka-1216

11 November 2026

To

The Headmaster

Government Laboratory High School

Dhaka-1000

Subject: Prayer for leave of absence in advance.

Respected Sir,

With due respect I beg to state that I am a student of Class 8, Section A, Roll No. 12 of your school. The marriage ceremony of my elder sister will be held on 16 November 2026 at our village home in Faridpur. As the eldest son of the family after my father, I must attend the ceremony and help my parents in the arrangements. For this reason, I shall not be able to attend school from 14 November to 17 November 2026.

I therefore pray and hope that you would be kind enough to grant me leave of absence for these four days in advance. I assure you that I shall collect the lessons from my classmates and try my best to make up for the classes I miss during my absence.

I remain, Sir,

Yours obediently,

(Signature)

Rahim Uddin

Class 8, Section A, Roll No. 12

Sample 2: Leave in Advance Application to the Principal for an Urgent Journey

This sample is written at SSC and HSC level. The recipient is the Principal (used for colleges and higher secondary institutions), and the reason is an urgent journey — another favourite examination situation.

12/B, Dhanmondi

Dhaka-1205

9 November 2026

To

The Principal

Dhaka College

Dhaka-1005

Subject: Application for leave of absence in advance.

Dear Sir,

I beg most respectfully to state that I am a student of Higher Secondary First Year, Science Group, Roll No. 45 of your college. My grandfather, who lives in our village home in Rajshahi, has suddenly fallen seriously ill. My father has decided to take the whole family there to see him, and our journey is fixed for 13 November 2026. The doctors have advised us to reach there as early as possible.

Under these circumstances, I shall be unable to attend college from 13 November to 18 November 2026. I therefore humbly request you to grant me leave of absence for these six days in advance. I shall be highly grateful to you for this act of kindness. I promise that I shall study the lessons taught in my absence on my return and sit for the class tests without fail.

Yours faithfully,

(Signature)

Tanvir Ahmed

HSC First Year, Science, Roll No. 45

Sample 3: Leave in Advance Application Written by a Parent

When the student is young (Class 6 or below), parents often write the application on the student's behalf. Examiners sometimes ask for exactly this: "Write an application on behalf of your younger brother/son." The format is the same, but the voice changes — the parent writes "my son/daughter" instead of "I."

House No. 3, Block C

Uttara, Dhaka-1230

10 November 2026

To

The Headmaster

Uttara High School and College

Dhaka-1230

Subject: Prayer for leave of absence in advance for my daughter.

Respected Sir,

With due respect I beg to state that my daughter, Nusrat Jahan, is a student of Class 6, Section B, Roll No. 8 of your school. We are going to our village home in Barisal to attend the wedding ceremony of my younger brother, which will be held on 15 November 2026. The whole family will travel together on 13 November, and we expect to return on 18 November.

I therefore request you kindly to grant my daughter leave of absence from 13 November to 17 November 2026 in advance. She is a regular and attentive student, and I assure you that she will complete all the class work and homework missed during these days with my full support at home.

I shall remain ever grateful to you for this favour.

Yours faithfully,

(Signature)

Mohammad Karim

Father of Nusrat Jahan

Class 6, Section B, Roll No. 8

Useful Phrases and Sentence Patterns for Leave Applications

Memorising a bank of standard phrases makes any leave application easy to write in the examination hall. Mix and match these to fit your own situation:

8. "I beg most respectfully to state that..."

9. "With due respect I beg to state that..."

10. "I am a student of Class ___, Section ___, Roll No. ___ of your school."

11. "The marriage ceremony of my ___ will be held on ___."

12. "I have to attend a family function at our village home."

13. "We are going on an urgent journey to ___ on ___."

14. "For this reason, I shall not be able to attend school from ___ to ___."

15. "Under these circumstances, I shall remain absent from ___ to ___."

16. "I therefore pray and hope that you would be kind enough to grant me leave of absence for ___ days in advance."

17. "Kindly grant me leave of absence from ___ to ___."

18. "I shall be highly obliged / grateful to you for this act of kindness."

19. "I assure you that I shall make up the lessons missed during my absence."

20. "I shall collect the class notes from my classmates on my return."

21. "I remain, Sir, yours obediently," (the standard closing before the signature)

22. "I shall remain ever grateful to you for this favour."

A quick grammar note for examination writing: in an advance application, use the future tense for the absence ("I shall remain absent," "I shall not be able to attend"), because the absence has not happened yet. In a post-facto sick-leave application, use the past tense ("I could not attend," "I was suffering from"). Mixing the two is the single most common mistake students make in this item — and the easiest to avoid.

Writing Tips to Score Full Marks

23. Read the question twice and underline the key words. If it says "in advance," "beforehand," "will be held," or "is going to," the examiner wants the permission-seeking advance style — not a sick-leave-after-the-fact application. Matching the style to the question is half the marks.

24. Follow the 7-part format exactly. Address, date, recipient, subject, salutation, three-paragraph body, closing with signature — examiners check format first. A missing subject line or date costs marks even when the language is good.

25. State the exact dates of absence, both first and last day. "From 14 November to 17 November" is correct; "for some days" or "for a few days" is vague and loses marks. Always write the dates as future dates in an advance application.

26. Give one clear, believable reason. A wedding, an urgent journey, a family function — pick one and describe it in two lines. Do not pile up three different reasons; examiners prefer one convincing reason over a list.

27. Use future tense for the absence. "I shall not be able to attend school" (advance) versus "I could not attend school" (post-facto). This single tense choice tells the examiner you understood the difference between the two application types.

28. Add the make-up promise. One line — "I shall try my best to make up the lessons missed during my absence" — shows responsibility and earns the examiner's goodwill. It is the finishing touch that separates average answers from full-mark answers.

29. Keep the tone formal and polite throughout. Use "beg," "pray," "humbly request," "kindly." Never use casual words like "want," "need," or "please give me leave." Formal vocabulary is what this item is testing.

30. Write neatly and keep the length moderate. About 150–200 words is ideal for this item. Do not write half a page of repeated requests — quality of language matters more than quantity.

31. Double-check the recipient's title. Headmaster for schools, Principal for colleges. Writing "Dear Sir" to a Principal is fine; writing "The Headmaster" when the question says "your college" is a format error.

32. Revise the dates and spelling in the last two minutes. Check that the application date is *before* the absence dates (that is what "in advance" means), and scan for spelling mistakes in common words like "absence," "ceremony," "faithfully," and "obediently."

Frequently Asked Questions

What is a leave in advance application for Class 6?

For Class 6, a leave in advance application is a short formal letter to the Headmaster asking for permission to be absent on upcoming dates. Keep it simple: your name, class and roll, the reason (usually a family wedding or journey), the exact dates from and to, a polite request, and the closing "Yours obediently." About 120–150 words is enough at this level. Sample 1 above is written at exactly this standard and can be adapted by changing the names, dates and reason.

How do I write an application for leave in advance for Class 8?

Follow the full 7-part formal format: address and date at the top, "To / The Headmaster" with the school name, a subject line ("Prayer for leave of absence in advance"), the salutation "Respected Sir," and a three-paragraph body. Paragraph one introduces you (name, class, section, roll). Paragraph two gives the reason and the exact future dates of absence. Paragraph three requests permission and promises to make up the missed lessons. Close with "Yours obediently," your signature, name, class and roll. Use future tense ("I shall remain absent") throughout, because the absence has not happened yet.

How to write a leave in advance application step by step?

Step one: write your address and the date (the application date must be earlier than the absence dates). Step two: address it to the Headmaster or Principal with the institution's name. Step three: add a subject line mentioning "leave of absence in advance." Step four: write the salutation. Step five: write the body in three short paragraphs — who you are, why you need leave with exact dates, and your polite request plus a make-up promise. Step six: close with "Yours obediently/faithfully," sign, and write your name, class and roll. Finally, re-read the whole application and check the dates, tense and spelling.

What is a good leave in advance application for SSC?

At SSC level, examiners expect a fuller application of about 180–220 words with slightly richer vocabulary. The reason is usually a family function or an urgent journey. Use phrases like "I beg most respectfully to state that" and "I shall be highly obliged to you for this act of kindness." The dates must be exact and in the future, and the closing should include a clear promise to make up missed lessons and sit for class tests. Sample 2 above is written at SSC/HSC standard — adapt the recipient to "The Headmaster" if your question is about a school rather than a college.

How do I write a leave in advance application to the Principal?

Write "To / The Principal" followed by the college name and address as the recipient. The salutation is "Dear Sir," (or "Madam"). Everything else follows the standard format: subject line, three-paragraph body, formal closing "Yours faithfully." The Principal is the head of a college or higher secondary institution, so this form is used for HSC-level questions. The reason should suit an older student — an urgent journey, a family emergency, or a relative's wedding — and the tone can be slightly more mature than a school-level application. See Sample 2 for a complete model.

What is the correct leave in advance application format?

The correct format has seven parts: (1) sender's address, (2) date, (3) the recipient (To / The Headmaster or Principal, with institution name), (4) a subject line such as "Prayer for leave of absence in advance," (5) the salutation ("Respected Sir," or "Dear Sir,"), (6) the body in three short paragraphs — introduction, reason with exact dates, polite request and make-up promise, and (7) the closing ("Yours obediently" or "Yours faithfully") with signature, name, class and roll number. The two special features of the advance format are future dates for the absence and a permission-seeking tone rather than a reporting tone.

Can a parent write a leave in advance application for a student?

Yes. For younger students, especially in Class 6 and below, it is completely normal for a parent to write the application. The format stays the same, but the parent writes in the first person about the child: "my daughter, Nusrat Jahan, is a student of Class 6..." and signs as the father or mother. The reason, dates and polite request are written exactly as in a student's own application. Sample 3 above is a complete parent-written model that you can adapt by changing the names, class and dates.

What is the difference between a leave application and a leave in advance application?

Timing and tone. A regular leave application is written *after* the absence — it informs the authority of what already happened ("I could not attend school yesterday because I was ill") and uses the past tense. A leave in advance application is written *before* the absence — it seeks permission for what is about to happen ("I shall remain absent from 14 November to 17 November as I have to attend my sister's wedding") and uses the future tense with request phrases like "kindly grant me leave." In examinations, the question tells you which one is wanted: words like "in advance," "beforehand," or "will be held" signal the advance form.
