You don't get a choice. If she is under 24 on Dec 31 she might qualify as your dependent if she was a full time student. Even if you don't claim her, she has to say on her return she CAN be claimed. But you said she was part time. I'm not clear on the Full Time rules. Maybe someone else can reply @xmasbaby0
