Education

If she meets the filing requirements with the W-2, she must file.  See below images for filing requirements

Did you pay any qualified education expenses out of pocket?  If you did not, you do not report the Form 1098-T.  How is the Form 1098-T reported?  If you receive a scholarship used for room and board or stipend, you need to report it.  Did the school report it anywhere else if not 1098-T?    My concern is if the school did report those income amounts, like stipend, room and board on any tax document, IRS will receive a copy and they will expect you to report it on your taxes.  You might want to contact your school to verify.
