As a high school teacher in a public school, I have found all of the responses utterly fascinating. When I applied for my job years ago, one of the interview questions was, "What would you tell a family who is considering private school rather than public school?"
My answer then was that public schools in the state had gotten the curriculum set up well, and that the kids were learning their subject matter at a higher level than I had been exposed to as a student.
Given the current trend to dismantle public schools by introducing charter schools and vouchers, forcing higher class sizes by state funding cuts, lambasting teachers, and forcing unattainable goals like 100% proficiency by 2014, I do not know what I will do with my daughter. This concern has only erupted in my life within the past three years, for I was confident in the schools before that.
Sending your children will only help dismantle public school education more. Soon, everyone will be required to pay for schooling, because the public school system will be gone.
I'm going to send my daughter to public school, as I had spent the extra money to buy a home in a school district that is to be envied, and I will review her curriculum and supplement it as needed to ensure she continues to have a passion for learning that she has right now.
Oh, and this: spoil your private school teachers rotten with gifts. They do not get paid enough. Well, that's true for all teachers in the U.S.
