A company who "recognizes 1% of high school students for their academic achievement". Each year, they publish a book with these students listed. Other perks include special scholarships you can win, a college referal system, and chances to join special educational experiences. Although it sounds wonderful, it really is more hype than anything else. I was recognized 3 years in a row (supposedly only 0.25% of American students get this "honor"), but I am still waiting to get something out of it. It's mostly an ingenious way of getting money from parents who wish to see their kid's name or picture in a book. I wish I would have thought of that

"Who's Who" has since expanded into colleges: Who's Who Among American College Students.
