<p>Would you be interested in a Catholic setting? You didn't mention, so perhaps not.
The social skills issue is the most important, in my opinion. I think living with other boys and having their influence rub off is way more important than the academics. Look for a school with friendly students, some of whom are goal-oriented. Your son hopefully would benefit from the low-key friendly environment, esp if you haven't praised him too much for his intellect, which might make him disdainful if the other students were not quite up to his level. In fact, his being smart might make him sought after for course help after hours, which could then lead in to his making friends and participating in social activities. </p>
<p>Good luck. This is such an issue. I can relate to it from personal experience.</p>
