From the very beginning, founder Dorothy Goodman envisioned that the school would educate children to become global citizens and the early curriculum reflected her vision.

In 1969, with assistance from the Ford Foundation, WIS expanded its campus with the purchase of the former Wendell Phillips School, which had closed a number of years before.

[5] In the early 2000s, WIS constructed an “arts, academics, and athletics building” (AAA) containing a gymnasium, choral and band practice rooms, and classrooms.

In 2021, the School launched a campaign to raise $30 million with the primary goal of constructing a new science centric facility on campus.
