Once the doctoral school has confirmed that I can register on ADUM, I follow the procedure.

If I have passed the ED competition, I can find the individual training agreement here.

I will find all the document I need to download on my ADUM space or on the institutions' websites (see below - institution procedures).

To register administratively, the Doctoral Studies Department of your institution (Lyon 1, INSA Lyon or ENS Lyon) will ask you for a certain number of documents and the payment of registration fees.
