It’s a little skewed because a lot of the people in these high schools aren’t Shomer Shabbos and Kashrus to begin with. My experience is that not so many have gone off. Unfortunately, I know that my experience has been very lucky and that most of the people I knew from these types of schools were raised properly and very Frum starting out. It is a problem in a lot of places. (I wonder what the rate is for graduates of “Yeshivish” Yeshivos?)
