Enriched by Differences

Our differences are what we have in common.

We are committed to being a community where all are welcome and valued, regardless of race, gender identity, sexual orientation, physical ability, ethnicity, socioeconomic status, cultural practices/beliefs, nationality, or perspective.

In recent years, diversity and inclusion have been at the center of discussions within most school communities. While we believe WIS has been an inclusive environment throughout its history (in accordance with the CIS Code of Ethics), there is always room for improvement. Our faculty, staff, and students participate in activities, events, and clubs that explore how we can learn from each other and express our ideas, beliefs, and opinions with empathy and civility.


A focus on IDI (international-mindedness, diversity, and inclusion) is one of the five key goals in the 2020 Strategic Plan. We established the following definitions so community members will have a common understanding of these terms.

International-Mindedness: A view of the world in which people see themselves connected to the global community and assume a sense of responsibility to its members. It is an awareness of the inter-relatedness of all nations and peoples, and a recognition of the complexity of these relationships. Internationally-minded people appreciate and value the diversity of cultures in the world and make an effort to learn more about them. (This definition comes from the International Baccalaureate.)

Diversity: The full range of differences and similarities — visible and non-visible — that make each individual unique.

Inclusion: The process of recognizing, valuing, and maximizing the opportunities that arise from having different perspectives and backgrounds.


Dr. Philip McAdoo performed an IDI Audit for WIS in late 2020/early 2021. He briefed the Board and the Parents Association Board, as well as faculty, parent, and student groups. His report identified five key areas to address in regard to IDI. The first of these was to clearly define terms; the core definitions are on this page. The information below lists past and ongoing efforts organized into the four areas identified in the IDI Audit. The charter for a Board IDI Task Force is also included below.


The 2023-2024 IDI Newsletter is available online.


  • WIS's new Director of IDI has begun his work as of the 2023–2024 school year.
  • THIS DOCUMENT explains WIS's approach to diversity and inclusion, as well as the intersection between IDI and the School's mission and approach to education. It is a complementary document to WIS's Communications Policy, which explains how the school approaches messaging around current events.
  • WIS's Speakeasy salons, launched in January 2023, use language learning as a lens to investigate international-mindedness.
  • A four-part IDI Lecture Series kicked off with a presentation on "Black in America" by Julian Hipkins. Lecture two was a parent session on international-mindedness led by Head of School Suzanna Jemsby. Lecture three was actress/songwriter Dara Reneé. Lecture four, an interactive session led by WIS teachers, introduced parents to tools teachers use to facilitate deep thinking in the classroom.
  • WIS sought community input on how the School can be more inclusive in its approach to recognizing religious and cultural observations.
  • Middle and Upper School Affinity Groups began meeting in the 2021–2022 school year. 
  • The school published a gender inclusion policy prior to the start of the 2021-2022 school year; all faculty and staff participated in related professional development.
  • The WIS Parents Association has committed to using its resources to support IDI initiatives and programming, and actively seeks involvement/leadership from all parents/guardians, striving for representation to mirror the student population.

The Mara Wilson Fund honors the memory of Mara Wilson, a WIS Middle School Art and Design Technology Teacher and artist whose work was defined by her love for her community and her vision for a more just and equitable Washington, DC. The fund is designed to support initiatives at the School that increase awareness about racial inequities; instill a culture that directly challenges and denounces racism; and cultivate a school environment where individuals of color feel safe and confident, and where all community members are equipped to recognize racial insensitivity and feel compelled to take action against it.
