It is understandable if considering the educational record (where s/he has studied and how is his/her transcript) of an applicant applied for junior academic positions such as postdoctoral fellow or assistant professor. BUT, for senior academics, the factors for judging a potential full professor is his/her research, teaching, publications, and other academic achievements.
I read in a few job ads for full professors in Europe (mainly Scandinavia), one of the application materials is unofficial transcripts. It seems that the initial review is substantially based on the applicant education achievements two decades ago.
I wonder how much the education of an applicant affects his/her chance to be appointed as a full professor? Does a bad education (having low GPA at PhD level) always affects someone's academic career, even at highest levels?
