The purpose of this study was to investigate school psychologists' attitudes toward lesbians and gay males. Aspects of school psychologists' knowledge, beliefs, current practices, and levels of preparedness related to issues of sexual orientation were also explored. A sample of 288 school psychologists (215 females and 73 males, mean age = 44 years) who were members of NASP participated in this study. Participants completed research packets containing a hypothetical case analogue vignette and three questionnaires querying their attitudes, beliefs, and knowledge about issues of sexual orientation. The results indicated school psychologists endorse relatively positive attitudes toward lesbians and gay males, report low-to-moderate levels of knowledge about lesbian and gay male issues, are willing to address lesbian and gay male issues on the job, are generally aware of how such issues impact schools, and are inadequately prepared to deal with lesbian and gay male issues. These findings are discussed in relation to their impact on the field and the implications for graduate training. (Contains 1 table.)
