ISK is a proud member of the Central and Eastern Schools Association (CEESA). As such, our secondary students (Grades 6-12) have the opportunity to participate in inter-school events throughout the year. A number of our after-school activities culminate in a trip for students within our CEESA region, including Cross Country, Knowledge Bowl, Football, Basketball, Choir, Speech and Debate, and more.
