You have just received your replacement assignment in the Versailles academy, and you are asked to log in to the Arena portal. The problem: your credentials do not work, or the portal displays an almost empty page. This situation affects a large number of substitutes, and the cause is almost never a wrong password.
Why Arena displays fewer applications for a substitute
Before discussing login or password, it is essential to understand a mechanism that traditional tutorials do not explain. The applications visible in Arena (I-Prof, Colibris, webmail, assignment tools) directly depend on your job profile registered in the HR system.

In practical terms, as long as your contract or replacement assignment has not been validated by the administrative management of your institution, certain services simply do not appear. You can log in without error, see the Arena homepage, and yet find only a handful of links instead of the expected dozen.
This dependency between technical authentication and administrative status explains the majority of the blockages reported by substitutes. The procedure for authentication on the Arena Versailles portal assumes that your assignment is already registered on the academy side. If this is not the case, no browser manipulation will change anything.

Synchronization delay of Arena rights: what really happens
Your academic account (the one that gives you an @ac-versailles.fr address) is created in a directory. The Arena portal, on the other hand, draws its permissions from another system. The synchronization between the two is not instantaneous.
Several unions in the Versailles academy, including SNES and SNUipp, have reported that the actual delay often exceeds internal communications. In practice, expect several days before your rights are effective on Arena, even if your academic email is already functioning.
Check if the problem comes from synchronization
A simple test: log in to your academic webmail. If the webmail login works but Arena remains empty or incomplete, the problem is indeed on the synchronization of permissions side. Your password is not the issue.
In this case, contact the secretariat of your assignment institution to verify that the replacement contract has been correctly entered. It is this entry that triggers the propagation of rights to Arena.
First Arena Versailles login: initial credentials and password
You have confirmed that your assignment is registered and that the synchronization delay has passed. Let’s move on to the login itself.
Your academic username usually takes the form firstname.lastname (sometimes followed by a number in case of homonymy). The initial password often corresponds to the NUMEN, this personal identification number assigned by the National Education. If you do not know your NUMEN, it is listed on your first appointment notification or can be requested from the HR service of your rectorate.
- Go to the official login page: id.ac-versailles.fr/arena
- Enter your academic username in the designated field (not your full email address, unless otherwise indicated on the screen)
- Enter the NUMEN as the password if this is your very first login, then follow the mandatory change procedure
Constraints of the new password
The system rejects passwords deemed too simple or already used. No visual alert always appears on the screen to explain the rejection. If the form seems to do nothing after submission, try a longer password, mixing uppercase letters, numbers, and special characters.
After several failed attempts, the account gets temporarily locked. This lock is lifted automatically after a certain time, without email notification. The Macadam platform (accessible via bv.ac-versailles.fr/macadam) allows you to reset the password or unlock the account.
Browser and cache: reflexes that avoid half of the errors
The official Arena Versailles login page mentions it itself: in case of a problem, clear your browser cache. This advice may seem trivial, but it resolves a significant proportion of blockages.
- Use an up-to-date browser (Firefox, Chrome, Edge). Older versions cause incompatibilities with the authentication system
- Clear the cache and cookies specifically for the domain ac-versailles.fr before trying again
- Avoid logging in from a filtered public Wi-Fi network, as some firewalls block exchanges with the academic authentication server
- If you use a password manager, ensure it is not injecting an old username into the form
Login via OTP
The Arena login page also offers authentication via OTP (one-time password). This option mainly concerns staff equipped with a token or enhanced security device. Substitutes generally do not have access to this during their first assignment. Ignore this button and use the standard form.
Applications accessible to substitutes after logging into Arena
Once logged in with full rights, the Arena portal provides access to several services useful for daily life. I-Prof allows you to consult your file, your assignments, and update your professional CV. Colibris manages leave requests and ongoing administrative follow-up. The academic webmail remains the official channel for exchanges with the institution and the rectorate.
Since recent school years, other tools have been integrated into the portal, notably the Inclusive Pathway Booklet (LPI). Substitutes assigned to positions with students with specific needs can access it directly via Arena, provided their job profile allows it.
If an expected application remains absent after several days, the most effective reflex is to contact the HR manager of your institution. It is the administrative validation of your assignment, not a technical parameter, that governs the appearance of services in your Arena space.
