Are these things considered?

@marvin100 , I see many students say this. They go to a competitive high school, but so do many students. I am genuinely curious as to why it matters. For instance, we live in a suburban county just outside a major metropolis. ALL the high schools around here are competitive. Do colleges want bragging rights to high schoolers? There are literally thousands of high schools where students do well on standardized tests and particpate in ECs. Do the colleges really know one competitive high school from another?

It seems to me that students mention their competitive high school more and more frequently. Or perhaps it’s just me noticing it. I would like to know why one competitive high school matters more than another.
