Question about college student filing taxes

We have a 20 year old college student who goes to school out of state (we are in TN, she is in NC), We have claimed her as a dependent on our taxes. She is filing taxes because of her scholarship income exceeding her tuition (by about $15K) She also has a job in NC while she is at school, as well as a summer job in TN.  Does she need to file in NC as well (TN has no state income tax) and, if, so, would it just be for her part time NC job (less than $5K).
