The Interactive Agents Portal (PIA) and Arena still coexist in the Grenoble academy, but their integration poses concrete problems whenever the agent profile is not synchronized with the academic directory. Understanding this convergence mechanism between the two portals prevents most access issues to business applications.
Synchronization of the academic directory and visibility of business components
The applications displayed in Arena, and by extension those accessible via PIA Convergence, depend on the agent’s profile in the academic directory: body, function, assigned establishment. This point is rarely documented in the usual connection guides, but it explains most cases where staff cannot find their tools after a transfer or change of function.

When there is a change of assignment, updating the profile in the directory can take several days, sometimes longer at the beginning of the school year. During this period, some business components may disappear from the portal or remain linked to the old establishment. We recommend checking directly with the management service of the DSDEN or the rectorate to ensure that the profile has been updated before seeking technical assistance.
To access all resources related to pia convergence and Arena Grenoble, the prerequisite remains an up-to-date directory profile; otherwise, neither professional messaging, Colibris, nor business forms will display correctly.

Authentication loops between PIA Convergence and Arena Grenoble
The redirection from PIA to Arena regularly fails in a loop after authentication. This malfunction, widely reported by users, mostly stems from expired cookies or corrupted session data in the browser.
Switching to private browsing resolves the issue in most situations. This is the first reflex to adopt before any other manipulation. If the loop persists, clearing the cache and cookies of the browser for the domain ac-grenoble.fr usually restores access.
Quick troubleshooting procedure
- Open a private browsing window and access the PIA address directly (pia.ac-grenoble.fr/portail/) or Arena (extranet.ac-grenoble.fr)
- If the problem persists in private browsing, manually delete cookies associated with the domains ac-grenoble.fr and education.gouv.fr in the browser settings
- Test with a second browser to isolate any potential extension conflict (ad blocker, password manager)
- As a last resort, use the technical assistance form accessible from the Colibris portal of the academy
These loops occur more frequently on shared workstations in the teachers’ room or in establishments, where multiple agents connect successively without closing the previous session.
PIA or Arena: which portal to use for business applications in Grenoble
Arena remains accessible at the historical address (extranet.ac-grenoble.fr), but its development has been halted in favor of PIA. The newer technology of PIA offers better adaptation to mobile devices and a tile interface that simplifies navigation.
However, we observe that some business applications still redirect to Arena in the background, even when initial access is through PIA. This technical coexistence is not transparent for the user: both portals share the same authentication system, but sessions are not always propagated correctly from one to the other.
Concrete differences between the two portals
| Criterion | PIA | Arena |
|---|---|---|
| Technology | Recent, responsive | Old, development stopped |
| Mobile access | Adapted for smartphones and tablets | Poorly ergonomic on small screens |
| Available applications | Same business components (via Arena redirection) | Complete historical catalog |
| Authentication | Academic ID or OTP key for directors | Academic ID |
For school directors, authentication on PIA accepts two modes: the messaging ID coupled with the OTP key (four-digit PIN followed by the six-digit code), or the classic academic ID. Assistants and other staff exclusively use the academic ID.
Lost ID or forgotten password: entry points to know
The ID recovery page of the Grenoble academy (bv.ac-grenoble.fr) allows users to retrieve their ID using the NUMEN and date of birth. Password reset is done through the same interface. These two operations do not require contacting the IT department.
The NUMEN appears on administrative appointment documents and on the payslip. Without NUMEN, the online recovery procedure is impossible and one must go through the establishment’s secretariat or the HR service of the rectorate.
A point of caution for staff recently appointed to the academy: the academic account is only activated after processing the file by the management services. Attempting to log in to PIA or Arena before this activation generates an error message that does not explicitly mention this delay, leading to unnecessary requests for technical assistance.
The convergence between PIA and Arena in Grenoble is progressing, but access stability still largely relies on the consistency of the directory profile and some navigation reflexes. Keeping your NUMEN accessible and prioritizing private browsing on shared workstations remain the two most effective measures to avoid recurring blocks.
