During Advisory on Wednesday, 16 students and one faculty member were inducted into the Park Tudor chapter of the Cum Laude Society, a national organization for secondary schools that recognizes scholastic achievement and encourages the qualities of excellence, justice and honor. Modeled after the college scholastic fraternity Phi Beta Kappa, the society was founded in May 1906, with the Tudor Hall chapter founded in 1941, followed by the Park School chapter in 1955. There are 376 Cum Laude chapters nationwide; Park Tudor is one of four schools in Indiana with a chapter.

Each spring, Park Tudor faculty who are members of the Cum Laude Society meet to elect the new members of Cum Laude. Membership in the Cum Laude Society is limited by its national bylaws to no more than 20% of the senior class. Juniors may be inducted, but this is limited to those few students who have received only grades of A for all semester grades at Park Tudor through the end of the fall semester of their junior year. Faculty who have been members of the Cum Laude Society at other schools are also invited to join the Park Tudor chapter.
