We believe that an environment that celebrates diversity is the best place to learn. We take the goal of educating the girls of The Hamlin School to meet the challenges of their time to heart in every aspect of our school. It is our mission to be an inclusive community where "diversity is a component of excellence and all members of the community are respected. We welcome and benefit from the perspectives that emerge from a diversity of ethnicity, culture, religion, socioeconomic status, learning style, sexual orientation, and family structure." The school seeks to promote student understanding of a multicultural society through professional development of the faculty, personnel, curriculum, programs, assemblies, and displays that underscore the diversity of our culture and the inclusiveness of our community.

Many important efforts are being made to communicate and establish Hamlin as an inviting community for greater ethnic and cultural diversity, greater socioeconomic diversity, better support for learning differences, better recognition of religious diversity, better support for different family structures and sexual orientation of our families. The work needed to bring everyone to greater and better awareness of the issues of equity and justice is substantial and ongoing.
