What does "top 10% of graduating class" really mean?

<p>S1’s public magnet school did not rank. It’s a school ranked within national top 5 among public schools. They did not want to penalize Johnny by showing him to be top 50 % when he easily could have been top 1% in other schools. (it’s a school with 60+ kids where 10+ are heading out to Ivies and another 10-15 or so end up with Top 20, non ivies). </p>

<p>S2’s suburban public high school in a very prosperous NE region decided NOT to rank from this year on, for the similar reason.</p>

<p>So, the picture emerging is, many of the high performing schools, both private and public, don’t report ranking, while more weaker HSs try to “help” their stars by providing ranks. </p>

<p>As such, in my opinion, the published report on % of the top 10% HS ranking students for colleges showing up on first few pages of USNWR report) are GROSSLY INFLATED, perhaps with the exception of top 10 schools or so - they would have gotten top, top, top students even from top, top, top high schools anyway.</p>
