How much of an impact does number of applicants from a single school matter?

<p>There are sooooo many amazing students out there coming out of average high schools it just seems odd a university that values diversity admits multiple students from the same high schools year, after year, after year, after year, after year… It seems odd a university that values diversity admits so many students from the least diverse high schools in the country. I guess diversity is only important in college.<br>
It would be cool if Stanford said next year we are only going to admit students from high schools that have not been represented for at least 10 years.</p>
