What being a Round Square school means to us

Round Square at Hackley is about connectivity- receiving exchange students and sending Hackley students to other schools, collaborating between classrooms, meeting peers at conferences, hosting visitors from other schools, and traveling as a group to global destinations.  Round Square has reached all parts of our community – parents, students, faculty, staff, and Board of Trustees – and our curriculum reflects the IDEALS throughout the school k-12.  Our proximity to New York City also allows Hackley to practice the IDEALS in a truly global metropolitan environment.
