What were the values of Whelton Academy, and how were they maintained?

In 1959, the Welton Academy is a somewhat old-fashioned but well-respected prep school where education is understood to be a rigorous academic learning program combined with the shaping of the students' characters according to explicitly traditionalist ideals. The film begins with a processional march of the students into the main auditorium of the school, where teachers and parents are awaiting the address of the headmaster Mr. Nolan (Norman Lloyd), who inaugurates the new school year by reminding everyone of the high standards of the institution, and the school's high success rate in sending its graduates to Ivy League universities.
