Four letters power a student’s entire administrative life — leave, OD, bonafide request, permission — and colleges assume you somehow know their formats. Badly-written requests genuinely get slower approvals; clean ones sail. Here are the formats with full templates, plus the unwritten etiquette that makes offices cooperative. (Colleges with portals/apps for these still expect the same content — and the paper letter remains the fallback everywhere.)
The universal skeleton (all four letters share it)
Top-left: From (name, register number, year/section, department). Below it: To (designation first — “The Head of the Department, [Dept]” or “The Principal”). Then Date, a one-line Subject (“Subject: Request for on-duty attendance – [event], [date]”), salutation (“Respected Sir/Madam”), a 2-4 sentence body (who you are → what you request → for when → why), a closing line (“Kindly grant…”, “Thanking you”), and Yours obediently/faithfully, signature, name. Short is professional; a page is a red flag.
1. Leave letter (to your class advisor/HOD)
Template: “Respected Sir/Madam, I am [name], studying in [year/section, department] (Reg. No. [x]). I was absent / will be absent from [date] to [date] due to [reason — fever/family function/personal reasons]. I kindly request you to grant me leave for the above period. I will complete the missed coursework promptly. Thanking you.” Etiquette: inform before the absence when possible (a message to the advisor, letter on return); attach medical certificates for sickness beyond a day or two — they matter if attendance ever needs condonation, and retroactive certificates convince nobody.
2. OD (on-duty) request — the one that protects attendance
Template: “…I have been selected to participate in [event — symposium/placement drive/sports meet] at [venue] on [date(s)], representing our college/department [attach proof: invite, registration, team list]. I kindly request you to grant me on-duty attendance for the above date(s).” The rules that matter: OD is prior permission, not retroactive forgiveness — file before the event through the prescribed route (advisor → HOD, or the events/sports department as your college specifies), attach evidence, and afterwards submit participation proof (certificate) where required. Filed OD counts as present; unfiled participation counts as absent, and that difference decides semesters (active students live on this letter).
3. Bonafide certificate request
Template: “…I require a bonafide certificate for the purpose of [bus pass application / bank account opening / scholarship application / passport/visa / internship application]. I kindly request you to issue me a bonafide certificate for the above purpose.” Etiquette: always state the purpose — offices word certificates to purposes and some (bank/embassy) need specific phrasing; apply days ahead (offices batch-process — the scholarship season queue is real), and request multiple copies at once when purposes are known.
4. Permission letters (events, gate pass, facility use)
Template (event/venue): “…On behalf of [club/class], we are organising [event] on [date] at [venue/time]. We kindly request permission to conduct the event and to use [hall/lab/equipment]. Faculty coordinator: [name]. Expected participants: [n].” Etiquette: route through your faculty coordinator’s counter-signature before it reaches the HOD/Principal — unsponsored student requests stall; sponsored ones move. For hostel/gate permissions, follow your hostel’s specific format and timing rules exactly — wardens run on their own procedures.
The office-wisdom layer
- Handwritten neatly or typed both work — legibility and completeness are what offices actually check (missing register numbers cause most rejections).
- Keep photocopies/photos of everything you submit — “I gave the letter” with no copy loses every dispute.
- Sequence matters: advisor → HOD → office is the respect chain; skipping levels annoys exactly the people whose signatures you need.
- Courtesy compounds: offices remember polite, organised students — and that memory surfaces when you need something urgent in final year (transcripts week, for instance).
