A lot has changed on the education front. I have kids in both private and public high school. It really is night and day. 5 years ago I would have said that a high achieving kid would do well at either and private school didn’t matter. I don’t feel the same way today. Some of my friends that are public school teachers feel the same way unfortunately including two that send their kids to private schools.We can argue how many, (some will argue even if any), of these kids were recruited. Moeller has a recruiting reputation going back to the 70s with Faust. We've all been around the block and realize that some of the religious schools do not live up to their stated values in terms of playing fairly and by the rules. I know of several instances at the Catholic grade school level.
As for a better education, IMO that is debatable. For students that come from strong families and reasonably good economic environment, their education is much more dependent on the student and the parents. There are pros and cons of going to a parochial school. I say that as a proud GCL alum.
