When to include degree classifications on a CV I've looked at some CV's from colleagues and superiors that I've worked with in academia, and one interesting thing I've noticed is that most of them don't mention if they've graduated with distinction (cum laude, first class etc), but for me it's crucial to mention. At what point is it not necessary to include? Does some amount of academic experience such as publications trump whatever the honors one received when graduating to the point where it's not necessary to include? Is this done because potential employers aren't interested after the person has a solid enough background in academia post graduation and degree conferral or is it simply not worth the whitespace?
I would mention it and leave it on your CV going forward. It is recognized and awarded by your university. Some people might discount it and others might not.
It is a minor thing, however, as it is normally simply a reflection of your GPA. And in applications that contain the GPA, that is a more precise indicator of where you wound up.
But it is an accomplishment, nevertheless and it is valid to be proud of it.
