While there is not an overwhelming amount of racial diversity at Lesley, with more than half of students being white, there is still a decent number of ethnicities represented by the student population. There are a few student-run organizations on campus representing minority students, including ALANA (African/Caribbean/Multiracial, Latino, Asian, Native American) and the Multicultural Club. In addition, Lesley has the Diversity Council that strives to support diversity-related efforts and hosts various diversity events both on and off campus. Various religions are also represented, with Lesley's Christian Fellowship and Hillel, Lesley’s Jewish organization, supporting students through meetings and events. Many students also follow the Buddhist and Hindu religions, and there are many places in the Cambridge area for students to practice these beliefs.
The most notable variety of diversity that Lesley has, however, is diversity of sexual beliefs and backgrounds. Lesley is probably one of the most open and accepting schools in this regard, and people of all beliefs and orientations are accepted. The two main LGBTQ groups on campus are Love And Equality for All People (LEAP) and Queer Lesley Education and Resources (QLEAR). Both organizations do a lot to support sexual diversity and host many popular events on campus, such as the annual LEAP Drag Show. No matter what type of minority, however, the students of Lesley are very accepting of all backgrounds and differences.
