Hawken currently has two main campuses, the Lower and Middle Schools in Lyndhurst and the Upper School in Chester Township, plus a third, an urban campus in University Circle, The Sally & Bob Gries Center for Experiential and Service Learning, which is utilized by all grade levels.

Hawken's motto is quoted from John Lancaster Spalding's Education and the Higher Life: "That the better self shall prevail, and each generation introduce its successor to a higher plane of life"; although a sign with the secondary motto, "Fair Play," hangs in every classroom on either campus.

In the fall of 2009, Hawken commenced a tablet computer program for grade 6 which later spread throughout the middle and high schools.

Designed by architectural firm Westlake, Reed, Leskosky, the project would bring the academic complex to 106,000 square feet.
