Ok, I have searched through a lot of past posts to learn about schools.

My question is about this tier system. It is clear what schools are considered to be at the top level. But what or who makes that determination?
Is it simply based on selectivity? Endowment?

Also, how do you determine "2nd tier".
We are looking at these schools: Loomis, Governor's, NMH, St George's and Westminster.
They all appear to be on that next level. Am I correct?

How does a family without BS connections find out this kind of information?

Thanks in advance.
