To which point is a paper considered as a "student contribution"? I am a PhD student, in the process of submitting a paper and I was asked to check (or not check) a box to state if :


  This contribution was solely written by students and/or doctoral candidates.


This paper was solely written by me as first author, with my supervisors as co-authors for reviewing. It deals mostly with measurements and their interpretation, which were done by me exclusively, the only non-original content is a figure I'm citing from another paper. However, my supervisors reviewed this paper, and also gave me advice during the research.

Is this sentence to be interpreted drastically (meaning I should not check it since the work is done by a supervised student, and not student(s) exclusively). And in a more general way, to which point would a paper be no longer considered as "student contribution" ?

This may seem obvious but I'm not familiar with publications processes since it's the first time I submit something.
In my experience, such declarations are typically defined in terms of authorship.  Thus, you will see, for example, a prize to be awarded for papers with a student first author, or for papers with only students as authors.

I would therefore generally interpret "solely written by" as meaning "all co-authors are."

If you want to be certain, however, it should not be any problem to request clarification from the organizers.
