<p>What would you hope to gain from disclosing this autism in his application? You’re under no obligation to, and I would recommend against it, unless you have a good reason to (he wants to use it in an essay, etc).</p>
<p>I would recommend, however, that he register with the disability services office at whatever school he goes to. He won’t have to disclose his diagnosis to his professors or classmates if he doesn’t want to, but the disability services office should be able to make the print larger/allow him to zoom in on his exams or give him other accommodations that he needs.</p>
