Reporting a 1099-Q

My grandson was the beneficiary of a 529 plan which was paid directly to the college.  The 1099-Q is in his name and SSN.  The entire distribution went towards tuition.  He also received a 1098-T from the school.  The amount of the distribution on the 1099-Q is the same as the amount reported in box 1 of the 1098-T.   His parents claim him as a dependent so he is not eligible for the American Opportunity Credit.  Does the 1099-Q get reported on his tax return or the parent's return?  Is the 1098-T reported on both returns?
