A bit of the counter-intuitive, of which I would agree: socialization best occurs in the family, not the school.
276. The family is the primary setting for socialization, since it is where we first learn to relate to others, to listen and share, to be patient and show respect, to help one another and live as one. The task of education is to make us sense that the world and society are also our home; it trains us how to live together in this greater home. In the family, we learn closeness, care and respect for others. We break out of our fatal self-absorption and come to realize that we are living with and alongside others who are worthy of our concern, our kindness and our affection. There is no social bond without this primary, everyday, almost microscopic aspect of living side by side, crossing paths at different times of the day, being concerned about everything that affects us, helping one another with ordinary little things. Every day the family has to come up with new ways of appreciating and acknowledging its members.
Any pro-school comments out there?

Well, if the family doesn’t include having to learn to self-manage on a near daily basis with peers vis-a-vis adults, something like school would become more important in socialization.
