Academic CV/grant proposal: Should you include students who have abandoned? I am wondering whether I should include students I have supervised but have quit in my CV, especially for grant proposals where supervision history is assessed. I have a couple of students who could not finish their programme, either because they didn't meet the academic requirements of our university or because of lack of funds. Do you think it would look bad on my CV to include them? If I do include them, should I explain why they quit?
For grant proposals in particular, this information can be used to assess conflict of interest. In fact, the National Science Foundation (NSF) moved that section off the biosketch to a separate document to make the intent of this section more clear. There, you could also indicate the last time you interacted, which may make the lack of relationship clear.

With grants, it is always essential to ascertain the purpose of the information to understand what information to present and how it should be presented. If you are unsure, you can always email the sponsor's help desk. They are typically fantastic in helping you understand the documents you need to assemble. Do not worry that they will assess your questions with your application.  PIs frequently worry about that, but that isn't happening.  They want good applications that are easy to review, so ask away!
