The Philadelphia Inquirer's Annual "Report on the Schools" was actually published yesterday, Sunday:
I had to do a comparison of the best public schools myself to justify the cost of private school and it's worth every cent. I toured Lower Merion, TE, and depending on your kids, the peer pressure and overall feel was that the girls, especially (as I have daughters that was what I paid attention to), grow up way too fast in public school and they have too much down time in public school to roam around, hang out, and be too wrapped up in social things instead of learning or activities.
I tried public school for a year for my oldest. I don't think there's a good public school out there as compared to private. The parents make all the difference and the parents at private school are into education, with exceptions to any rule of course. Nothing is perfect.
