Trying to live, discipline, work, teach, socialize, play sports with an underlying moral code. I have witnessed this implemented and succeed and will be forever grateful to the teachers, parents and administration at my child's school
This. My kids were in a private Catholic school for two years. We lived in a part of the county where the public schools were just not an option. They've been in public school everywhere else we've lived.
It wasn't the academics that made the difference. It was the environment. Their Catholic school stressed fairness, kindness, morality, compassion, and discipline. Doing the right thing was more important that achieving the desired goal. Their Catholic High School was amazing! Very few discipline problems. No bullying that I ever heard of. Just a general atmosphere of acceptance and friendliness.
And 30% of the student population was non-Catholic.
