Hi,
I am starting to research schools for my son. Can anyone recommend a book(s) that helps to identify certain criteria or standards that a school should have to educate and prepare students. I understand some of the basics but would like to be informed when I start searching for schools. For example, what are the schools doing that have their students admitted to the top Universities, such as Princeton and Harvard? I would appreciate any references that you could provide. Thanks!

Best,
Diane
