Is my daughter considered a full-time student if she graduated college in May 2018?

[DoninGA]

Yes she would be a full time student if she was classified by her school as full time and she attended classes for any part of a month from January thru May.

Yes, she is.  

According to publication 17, she is a full-time student if she is enrolled at a school for the number of hours or classes that the school considers full time. She must be full-time for some part of each of 5 calendar months during the year. (The months need not be consecutive)
