This link is to a 28 page thread on another forum (Chronicle of Higher Education). Some good laughs and some good advice for anyone submitting CV's, but particularly those who graduated this spring. A few duds as well, but one has to expect that in 28 pages worth of opinion. https://chronicle.com/forums/index.php/topic,39038.0.html
don't omit degree dates? I disagree. I think 20+ old degrees contribute to creating some potential age-discrimination, and in my case, I returned to school as an adult, so I feel like it creates questions (1990 and 2014?) instead of answering them. I learned that tip here, and have used it ever since.
A number of people in that thread agree with you. Unfortunately, whatever we put on our CV's I think that latitude disappears when the HR forms require dates.
I fully expect that if my resume/cv isn't tossed in the trash at first glance, that my degree dates would be added to some form or at least verified. I think that thread, as long and old as it was, really only relates to hard-core academic aspirations, so might not apply to the average Joe.
I don't bother with degree dates on my resume, though I've never done a CV, so its conventions are outside of my collection of knowledge. For my purposes, the degree date is a waste of perfectly good ink. I can see some fields where the degree date may be important, however. A computer science degree from 1970 won't do you much good in 2014, for example, unless there is a whole lot more that has happened since 1970 that demonstrates that you are capable of working in today's technological environment.
It all depends on work experience. If the person with the 1970 computer science degree has worked in the field since the 70's, I would rather hire them They have a greater range of experience.
