<p>I don’t include parochial schools when I say private schools, colleges put them in a separate category. </p>
<p>35% are from independent private schools, more at many good LACs. </p>
<p>There are many elite private high schools in the country along with those you name. At least 35 in the greater NYC area. Probably close to as many in Greater Boston, The SF Bay Area has a dozen or more as does LA, DC, Chicago…and we haven’t even touched elite publics. This is a lot of schools, and while “random” schools are becoming better represented, the public and private elites still account for most kids at elite colleges.</p>
