Full time students and personal exemption

My son was a full time student through May of 2016, when he graduated.  He then moved out of the house in July 2016, starting his new job on the 7th of July.  We paid for over half his expenses while he was a student, but he has paid 100% of his expenses since July 7th (yes, a miracle!) - does the requirement that we pay more than half his expenses only apply during the time he was a full time student or is it for the full year?
