Ok here also. The good thing about 12 years of Catholic school was the education. Where I grew up we were way ahead of the local public schools and just passing was never automatic. One actually had to work to graduate. As far as staying a Catholic goes I have heard many use the expression "I'm a recovering Catholic" and do understand what that means. To answer your question I have to believe one would be more apt to stay catholic after attending 12 years of catholic schooling.
