In 1991 members of three religious congregations in Sudbury, Massachusetts, one Jewish, one Roman Catholic and one United Methodist, initiated Students Together Opposing Prejudice (S.T.O.P.) to educate junior high school youth about discrimination, prejudice and stereotyping. Rev. Avis Hoyt-O’Connor, Sheila Goldberg, and Susan Murphy developed S.T.O.P. in response to an anti-Semitic incident at a local elementary school. The goal was to teach students about discrimination and to provide them with skills to become agents of change in their community.
