I spent the first 10 years of my education in Catholic parochial schools.
Grade 1-8. The nuns beat those troublemakers with pointers or yard sticks.
Grade 9 and 10 the Marist Brothers would expel you for just a hint of being out of control. I moved to the burbs and attended public school for grades 11-12. This was the 50s and 60s.
Sounds about right. My older sisters both teachers said they weed out the problems early.
The nuns would make us kneel in front of the classroom statue of the Blessed Mother. Length of time on our knees depended upon the severity of the misbehavior.
