College student claimed as dependent

I have a 21 year old full time college student. He received a few W-2s from jobs he has had and a 1098T from college. The 1098T has $13,039 in box 1 and $18,836 in box 5. He made over $15,000 with his W2's.  I am claiming him as a dependent. When he files his taxes, he checks I can be claimed as a dependent as someone else's taxes. He also claims the 1098T, correct as taxable income, correct? 

Thank you!
