Pros and cons of catholic school?

I am from inner city Philadelphia and my son started school recently he’s only 3 years old and it’s sort of a pre-k thing they are doing. He has been having problems in school since he started other children have been “bothering” him and he came home the other day with 3 big scratches on his face. The people at the school first started off sayin it was an accident that was what was told to us on the incident report they made and had us sign then when trying to get more info it was revealed that he got into a fight with one of the other “kids.” This has caused us to not trust the school and maybe try and get him into another school or program. His mother is religious and she was saying we should try to get him into a catholic school. As someone who is not religious could anyone give me some pros and cons to the situation. Thanks on advanced and sorry for the formatting. via /r/Parenting http://ift.tt/2otGaQT
