You have just been assigned to the Grenoble academy, or you are changing positions after the start of the school year. The first reflex: find your online work tools. The PIA Grenoble portal and Arena bring together almost all the professional applications used by agents of the National Education in this territory. Knowing where to click, with which credentials, and in what order avoids wasting precious time in the first days.
Partial PIA-Arena merger: what has changed for agents in Grenoble
Since January 2025, PIA and Arena have been partially merged in the Grenoble academy. Specifically, the national professional applications (i-Prof, GAIA, SIAM, LPI, exam management) are now accessible directly from the PIA portal, without switching to Arena.

Other academies, such as Orléans-Tours, still maintain two completely separate portals. In Grenoble, this convergence simplifies daily tasks: a single entry point is sufficient for the majority of administrative and educational tasks.
Arena remains available at its historical address, but its development has been halted. Agents who wish to access Arena Pia Grenoble therefore go through PIA to benefit from the most recent interface, then find the same applications as before.

Academic identifier and SSO: a single session for multiple applications
You may have already noticed that after logging into PIA, you can open i-Prof or your email without re-entering your credentials? This is the mechanism of SSO (Single Sign-On) that manages this. A single username-password pair grants access to all internal services.
The academic identifier generally takes the form of firstname.lastname. It is constructed from your NUMEN, the identification number specific to each agent of the National Education. The associated password is that of your national education account.
Two authentication modes depending on your profile
All agents use their email identifier and password. School directors also have an additional option: the OTP key (four-digit PIN followed by a six-digit code). This second mode adds a layer of security for sensitive operations related to management.
In case of forgetfulness, three common situations call for three distinct actions:
- Forgotten identifier: the “Retrieve your identifier” page on the academy’s website allows recovery based on personal data.
- Forgotten password: the reset procedure goes through the dedicated form of the Grenoble academy, accessible without prior login.
- No functional access: the academy’s support portal accepts requests even without authentication, via a specific form.
Mobile-first interface and remote access to professional applications
The redesign of Arena in 2024 introduced a mobile-first interface optimized for smartphones and tablets. This technical change has concrete effects for agents on the move or visiting establishments.
Before this redesign, consulting a professional application on a phone was a challenging experience: truncated menus, buttons too small, slow loading. The current interface adapts the display to the screen size, making navigation smooth even on a small format.
Configure academic email on a personal device
Why configure an external email client instead of using webmail? Because notifications arrive in real-time, without opening the browser. The specific technical settings for the Grenoble academy are as follows:
- IMAP incoming server: imaps.ac-grenoble.fr, port 993, secure connection SSL/TLS.
- SMTP outgoing server: smtps.ac-grenoble.fr, port 465, secure connection SSL/TLS.
- Identifier: your complete academic email address ([email protected]).
These settings work on both the native mail applications of Android and iOS as well as on clients like Thunderbird or Outlook.
Colibris, PIA, and Arena: how the three portals are interconnected
Colibris is the national platform of the National Education that centralizes certain collaborative services. In Grenoble, Colibris also serves as a complementary access point to several tools available elsewhere on PIA.
The logic is simple. PIA is the main academic portal, the one you use daily. Arena remains the old portal, still accessible but frozen. Colibris, on the other hand, provides cross-functional services that exceed the scope of a single academy.
For an agent in Grenoble, the most direct route remains to go through PIA. The national applications have been grouped there since the partial merger. Colibris mainly intervenes for collaborative tools or inter-academic training.
Adjusting shortcuts to save time
Saving the PIA Grenoble address in your browser favorites may seem basic, but it is the action that saves the most time over a school year. The official address of the PIA portal is pia.ac-grenoble.fr/portail/. The address of Arena, still functional, is extranet.ac-grenoble.fr.
A shortcut on the phone’s home screen, pointing to PIA, transforms the portal into a near-application. On mobile Chrome, the “Add to Home Screen” function creates this icon in seconds.
The convergence between PIA and Arena in Grenoble reduces the number of portals to remember. One favorite link to PIA covers the majority of daily needs of a teacher, administrative staff, or director. Agents who keep a shortcut to Arena lose nothing but go through an interface that no longer receives updates.
