Teachers' tolerance and their attitudes toward diversity were studied through a survey of 521 graduate and undergraduate students. The majority of the graduate students were teachers pursuing master's degrees, and most of the undergraduates were in preservice teacher education courses. The surveys were related to political, social, and moral diversity. In addition to the survey responses, information on teacher attitudes was drawn from 8 focus group interviews with 77 inservice teachers, 18 whole class discussions, and 22 open-ended questionnaire completed by students. Most of the attitudes held by these educators were well-formed and not susceptible to change by comparatively fleeting influences, such as a discussion of issues. Intolerant beliefs and attitudes were held more strongly (as is the case with the general public) than tolerant beliefs or practices. Teachers and future teachers differed widely in their level of tolerance for diversity, and their responses were distributed almost as widely as those of the general public. Few extreme conservatives or extreme liberals were found. (SLD)
