My son received a 1098-T. I am claiming him on our taxes. Do I also report the 1098-T on his?

Yes, you can include his 1098-T on your return to claim an education credit if his scholarship/grant amount in box 5 is less than tuition and expenses in box 1 or 2.  

If his scholarships and grants were more than his qualified tuition expenses then the excess is taxable income and he needs to include it on his return.
