<p>Take home message from the sticky is that for college admissions you are Hispanic if you identify as Hispanic. So yes, if you identify as Hispanic via your great grandfather from Spain, then you can mark Hispanic.</p>

<p>Being Hispanic can help in college admissions, but the degree to which it helps depends on: the school, your academic and outside achievements, and the other types of factors cited in the thread I linked to. </p>

<p>There is nowhere on college apps where they ask what percentage Hispanic you are. The main point, and one ONLY you can answer is: do you identify with your Hispanic culture? If you do, then you should have no problem checking the box, if you don’t, then you shouldn’t. There are many factors beyond the percentage of Hispanic background you have that affects how much, if at all, you identify as Hispanic, so this is a very personal issue. Be honest and you can’t go wrong.</p>
