Yes Haverford is not Williams. It is better in a lot of its own ways. Williams is tops in many minds but not for everyone. They have their own challenges. Leave it at that.
Back to the topic that was asked.
My take is this has a value or is indicator to them of a meaningful characteristic. it is part of that equation some schools really value versus others, we are so often asked here on CC to divine for families.
So I looked at the Boston College fact book. And I recall it was 80+ percent where top 10 percent of their class. Considering the big time sports recruits in the mix, I thought it was a big number.
So perhaps that has more weight for certain schools as indicator of something they believe offers some view into the application of what works at their school, to determine their best class. Or who will be successful there.
It was insightful for me as we look at profiles and questions from posters asking for a sense of their application to school x or y.
As a example for nuanced view of things, the top 10 and 4.0 unweighted with a lot of APs with the 1450 is better opportunity for Haverford or BC, perhaps. Versus the 1540 outside the top 10 with the 3.7. Ecs essay recs and rigor all being equal of course.
