A missed class due to gastro, a failed exam because of a train breakdown, a medical appointment that cannot be rescheduled: each situation requires an appropriate absence justification, and most university secretariats now refuse poorly written documents or those submitted late. Knowing which document to produce, in what form, and within what timeframe helps avoid the mention of “unjustified absence,” which can lead to a zero in continuous assessment or exclusion from an exam.
Digital submission of absence justification: what has changed at university
In recent years, an increasing number of universities have mandated that justifications be submitted exclusively via the ENT or an online form, with scanned documents uploaded. Paper submissions to the secretariat or simple email submissions are no longer accepted everywhere. The University of Bordeaux, for example, uses the PJweb application to centralize these documents in the student’s administrative file.

Specifically, you prepare the document, scan or photograph it neatly, and then submit it on the dedicated platform. Check the submission channel before drafting the justification to avoid wasting time sending a letter that no one will process.
Regarding deadlines, the most common rule remains submission within 48 hours after the start of the absence. Beyond that, even a legitimate reason can be reclassified as an unjustified absence, as specified in the regulations of CREPS Rhône-Alpes or the University of Tours.

Acceptable reasons for absence at university: medical certificate, summons, and force majeure
Not all absences are justified in the same way, and certain reasons require a specific type of document. Three main categories are distinguished in most study regulations.

Absence for medical reasons
A work stoppage (or sick leave) remains the strongest justification. One often overlooked point: a simple medical certificate without a stoppage is not always acceptable. The University of Tours explicitly reminds this in its study regulations. For a sick child, a medical certificate in the child’s name is generally accepted, provided it is submitted within 48 hours.
A scheduled medical appointment during a class or lab slot rarely justifies the absence on its own. Some universities only accept it if the student proves that no other slot was available. When in doubt, attach the practitioner’s certificate specifying the time and date of the appointment.
Official summons
Some summons automatically serve as justifications:
- Summons for the driving license (practical or theoretical exam), to be attached as is to the file.
- Pôle Emploi (France Travail) summons as part of an integration or training program.
- Judicial or administrative summons, with the official stamped document.
For high-level athletes listed on the ministerial list, a summons to a competition is accepted as long as it corresponds to the preliminary schedule validated in advance with the training coordinator.
Force majeure and family events
The death of a spouse or a first or second-degree relative entitles one to a justified absence upon presentation of a death certificate or act of death. For external events (transport breakdowns, natural disasters), universities increasingly require material evidence such as a carrier’s certificate or a dated newspaper clipping. Responses on this point vary among departments: some UFRs still accept a simple written declaration, while others do not.
Affidavit for absence at university: an increasingly rejected recourse
For a long time, writing an affidavit was sufficient to cover a non-medical occasional absence. This practice is becoming more restricted. Several institutions now specify that affidavits are no longer acceptable to justify activities related to studies, work, or income.
The affidavit is only accepted for situations that cannot be documented with any official certificate, such as a serious domestic issue without documented external intervention. In all other cases, a third-party document must be produced: employer’s certificate, medical certificate, summons.
If you must still resort to this format, the writing must be precise: full identity, date and time of absence, detailed reason, handwritten signature (or electronic if the submission is digital). A vague text like “absent for personal reasons” will be rejected by most administrative offices.

Writing an effective absence justification: structure and mistakes to avoid
A rejected justification is rarely due to the reason. The problem almost always lies in the form. Here are the elements that each document must contain:
- Header with name, first name, student number, department, and course followed.
- Clear subject mentioning “absence justification” followed by the relevant date.
- Body of the message indicating the specific reason, duration of the absence, and the associated attachment (sick leave, summons, certificate).
- Simple polite closing and signature, with contact details (preferably university email).
Sending the justification from your university email address enhances its credibility. Secretariats often filter messages coming from personal accounts like Gmail or Outlook, especially when the volume of absences to process is high.
Another common pitfall: attaching an illegible scan. Ensure that the resolution is sufficient, that the document is in PDF format, and that all information (stamp, doctor’s signature, date) is visible. A truncated or blurry file will be treated as an unjustified absence while waiting for a new document, and the 48-hour deadline will likely be exceeded.
The trend towards digital formalization of absence justifications is not going to reverse. Preparing a standard template saved on your computer, with pre-filled fields (identity, course, student number), allows for quick action on the day the absence occurs. The time saved on drafting translates into respecting the submission deadline, which remains the determining criterion for an absence justification to be accepted.
