From Harlow Unger's `How To Pick A Perfect Private School'--Part 1:

In his 1999 book, How To Pick A Perfect Private School, Harlow Unger indicated how the U.S. power elite's private school system differs from the U.S. public school system:

"Instead of about 25 students per teacher, as in public schools, private schools assign only about a dozen students to each teacher (9.8 in independent schools that are unaffiliated with any church or government agency), thus guaranteeing the individual attention each child needs to thrive intellectually...

"Unlike private schools, public schools are required by law to accept all children in the school district, and a teacher has no choice but to admit them into the classroom...Private schools try not to admit...unruly children...The handful that slip through are summarily expelled as soon as they begin to disrupt school routine...Private-school teachers are thus free to devote all their time to teaching instead of dealing with disciplinary problems..."
