Athletics has been an integral part of the Upper School program since the School was started in 1919. Perry Dunlap Smith, the founding headmaster, believed a school required its students to exercise both mind and body. Therefore, North Shore has always had a strong, varied athletic program. Participation in the interscholastic program is required from 9th through 11th grades.
All new students are required to play a team sport in the fall. This requirement has as much to do with athletics as it does with helping students have a successful transition into the Upper School.

After their first year, students are required to play at least one season of athletics through 11th grade to fulfill their athletic requirement.
North Shore Country Day School is a junior kindergarten through 12th grade, college-preparatory school founded in Winnetka, Illinois in 1919.  With rigorous academic pursuit as the cornerstone, North Shore provides many opportunities for all students to excel – in the classroom and the laboratory, on the stage and the playing field, in their communities and beyond.
