Annual survey on the opinions and satisfaction of UNICAM PhD students for the activities carried out in the previous year is carried out using a questionnaire. The survey is, however, anonymous and the system is set up with separate tables so as not to allow operators to trace the Respondents in any way. For the 2023 survey on the activities carried out in 2022-2023, 338 students enrolled in the 6 PhD courses active in UNICAM were invited. The PhD students involved are distributed over 4 cycles, from the 35th to the 38th. The survey was open from 6 to 31 October. The percentage of Respondents was 76,6% (259).
