If you insist, I must point out some errors. While true that standards are different from public to private schools, the myth about certification is a couple decades old. While it's possible to get HIRED without a cert, you'll need to get it within a year or two.
Also, parochial schools only pay about 15% less (on average) then public schools, and that's namely because they charge lower tuition. Parochial schools are VERY diverse now, so that kills the myth that the students are easier to teach. If you look at Montessori schools, who charge top-end prices, salaries are the same.
The class size myth is also just that, especially in parochial schools. In MOST cases, public schools are actually much better funded, and can afford smaller class sizes. I have also yet to see a study that was NOT in some way funded or vested in or by Teachers unions that show any proof that small class sizes equal success. In fact, all the math I'm seeing out of the Chicago public schools (where only 6% of students go on to graduate from a 4-year University within 6 years of graduation) is about 13 or 14/1 student/teacher ratio.
So, anyway, not to hijack the hijacking of my thread, but...gotta stick with the facts if you're gonna do this.
