The absence excuse letter is a two-minute job that parents somehow end up writing on the kitchen counter at 7:40am. It is simple, but schools are particular about what it contains — get the pieces right and the absence is recorded as explained; miss them and it can sit on your child's record as unexplained, which in some systems feeds into attendance warnings nobody wants. Here is the whole process, in order.
Schools differ more than you'd expect. Many ask for two things: contact on the morning of the absence (a phone call, voicemail or a message in the school app) and a written note when the child returns. Some accept an email to an attendance office as the written note; others want paper, signed. There is usually a deadline too — a note within a few days of the child's return is a common pattern. Five minutes with the school handbook or a quick call to the office tells you exactly which version your school wants.
Call or message before school starts, on the day itself. Keep it to one line of substance: your child's name, their class, and the reason — "high fever", "stomach bug", "dentist appointment" — plus how long you expect the absence to last if you know. This morning-of contact is what protects your child in that day's register, and in some schools it is also what triggers work being set aside or sent home. If the absence stretches beyond what you first expected — a fever that lingers, a bug doing the rounds of the family — update the school each morning rather than going quiet; a school that knows the situation rarely chases, and your child is not marked down for your silence.
The written note itself needs five pieces of information, and very little else:
Keep it factual and brief. Schools process hundreds of these; the reason category is what gets filed, not a symptom-by-symptom account. And keep it honest — vague, rotating reasons invite questions later that a straight note never would.
Add one line to the note, or send it as a separate message: "Please let us know what work [child] should catch up on." Schools handle this differently — work sent home with a sibling, an online portal, notes from a classmate — but asking signals that the absence was genuine and gets your child the material before small gaps quietly become big ones. For absences of more than a day or two, it is worth a direct word with the teacher as well.
Many schools require medical evidence once an illness absence runs to several consecutive days — three or more is a common threshold — or around exam periods. This doesn't usually mean a formal letter: a brief note from the clinic, or even a stamped appointment card, is often enough. Check what your school accepts before you pay for anything. And if absences are becoming frequent because of an ongoing health condition, talk to the school early rather than note-by-note — many schools can put a proper support arrangement in place, which is easier on everyone.
Our free School Absence Letter Generator asks for exactly the five pieces above — name, class, dates, reason, your details — and produces a clean, correctly formatted note you can print, copy into an email, or paste into the school app.
School policies vary — absence categories, note deadlines and evidence rules differ by school and by country. If in doubt, your school's office or handbook is the final word.
