====== Note for PhD students and supervisors ======


Per i dottorandi che completano il secondo anno, la presentazione vale come valutazione dell'avanzamento. Sarà cura di ciascun dottorando e del supervisore fare in modo che la commissione sia presente alla relazione. Se necessario, la commissione potra` richiedere in tempi brevissimi un approfondimento prima di rilasciare il proprio giudizio.

I dottorandi che completano il terzo anno presentano il loro lavoro di tesi (che deve ancora esser valutato dai revisori esterni; dopo la revisione, sarà nuovamente discusso davanti alla commissione interna.)

----

The presentation of the PhD candidates completing their second year has also the purpose of assessing the advancement to the third year. PhD candidates and supervisors should make sure that her/his commission is present at the presentation in the workshop. If necessary, the commission may request further discussion, immediately after the workshop, before completing its review report about the PhD candidate.

The presentation of the PhD candidates completing their third year has the purpose of illustrating the current status of their PhD thesis (which will be evaluated by the external reviewers and, after receiving the referees' reports, will be reviewed and defended with the internal committee.)
