OP can look at the present numbers or percentage of Hispanics, at various colleges. At Bowdoin, eg, it’s 11%. While that’s lower than the national average in the US population, more is considered than that. He needs to match adacemically and in activities, too. There’s a large pool of highly qualified kids in Texas who apply out of state. Where OP lives could make a difference in the competition he faces, even at LACs.
