This article presents a methodological critique of the few attempts to promote tolerance for homosexuality through education. Thedstatistic was utilized to assess the extent of attitude change from pre‐to post‐intervention assessment. With few exceptions, data have been gathered from college students in courses focused on human sexuality. These data suggest that students who complete these courses become less fearful of contact with homosexuals, more tolerant of homosexuals in social roles, and more tolerant of homosexual behavior, although the extent and duration of the changes may be limited. Although some attribute attitude change to the intensiveness of the course, methodological and conceptual problems, including volunteer bias, provide alternative explanations. Further attempts to promote tolerance toward homosexuality must consider differences in attitudes toward gay men and lesbians and the extent to which men and women differ in their level of tolerance toward these groups.
