This made me pause and think for a moment. What do rich kid schools do? I have no idea. I went to a dumb kid rural high school. But for some reason through the endless education discussion I've never heard brought up what rich kid schools do differently. Even if the answer is "but we can't do that because we're poor". Man. Now you've got me all curious...
One thing "rich kid schools" do is filter out many students who are difficult to teach. Teaching and running a school is a lot easier if your goal does not involve teaching everyone who walks through your doors.
"Just" the facts of very interested parents, investment from nearby Intel and HP, and massive spending on technology programs were enough to set this school apart. Sometimes the simple answer is the right one.
