The student who asks for an internal transfer (course shift in Politecnico) doesn’t have to define plan of study before submitting the request; he/she will have to wait for the approval of the shift and then go to the Registrar’s Office for the plan of study definition. 
In the same way, who wish to leave and go in another university doesn’t have to define plan of study before submitting the request.
Who transfer to Politecnico asking for an evaluation of a previous career can define plan of study at Registrar’s Office desks just after having received the note of the evaluation commissions in charge. Commissions evaluate the curricula requirements. For further information see the section On-line Registrar’s Office Trasferimenti/Transfer.
