Key word I want to point out in Opus 17's correct response, is "joint return". If he files MFS (meaning his spouse must file her own MFS return if she has reportable income of her own), and does *not* take the self-exemption, then (and only then) can you claim him as a dependent and also claim all the education credits. My response has nothing to do with the 1098-E student loan interest. So hopefully you're not confused.
