I have never attended a public school. I attended parochial schools from kindergarten through 8th grades, a private high school, a private college, and a private graduate school. I am the only member of my family of whom that is true. All of my siblings attended public high schools and most attended public colleges. My youngest siblings also went to kindergarten at a nearby public school since our parish’s school didn’t have a kindergarten.
My parents both attended public schools K-12. My dad attended private undergraduate and graduate schools. My mom attended a public undergraduate school and a private graduate school.
I’m not citing my experience as an advantage. In some ways I think it was a disadvantage. It’s merely a fact.
